-## Voice Activity Detection (VAD)
-Support for Voice Activity Detection (VAD) can be enabled using the `--vad`
-argument to `whisper-cli`. In addition to this option a VAD model is also
-required.
-
-The way this works is that first the audio samples are passed through
-the VAD model which will detect speech segments. Using this information the
-only the speech segments that are detected are extracted from the original audio
-input and passed to whisper for processing. This reduces the amount of audio
-data that needs to be processed by whisper and can significantly speed up the
-transcription process.
-
-The following VAD models are currently supported:
-
-### Silero-VAD
-[Silero-vad](https://github.com/snakers4/silero-vad) is a lightweight VAD model
-written in Python that is fast and accurate.
-
-Models can be downloaded by running the following command on Linux or MacOS:
-```console
-$ ./models/download-vad-model.sh silero-v5.1.2
-Downloading ggml model silero-v5.1.2 from 'https://huggingface.co/ggml-org/whisper-vad' ...
-ggml-silero-v5.1.2.bin        100%[==============================================>] 864.35K  --.-KB/s    in 0.04s
-Done! Model 'silero-v5.1.2' saved in '/path/models/ggml-silero-v5.1.2.bin'
-You can now use it like this:
-
-  $ ./build/bin/whisper-cli -vm /path/models/ggml-silero-v5.1.2.bin --vad -f samples/jfk.wav -m models/ggml-base.en.bin
-
-```
-And the following command on Windows:
-```console
-> .\models\download-vad-model.cmd silero-v5.1.2
-Downloading vad model silero-v5.1.2...
-Done! Model silero-v5.1.2 saved in C:\Users\danie\work\ai\whisper.cpp\ggml-silero-v5.1.2.bin
-You can now use it like this:
-
-C:\path\build\bin\Release\whisper-cli.exe -vm C:\path\ggml-silero-v5.1.2.bin --vad -m models/ggml-base.en.bin -f samples\jfk.wav
-
-```
-
-To see a list of all available models, run the above commands without any
-arguments.
-
-This model can be also be converted manually to ggml using the following command:
-```console
-$ python3 -m venv venv && source venv/bin/activate
-$ (venv) pip install silero-vad
-$ (venv) $ python models/convert-silero-vad-to-ggml.py --output models/silero.bin
-Saving GGML Silero-VAD model to models/silero-v5.1.2-ggml.bin
-```
-And it can then be used with whisper as follows:
-```console
-$ ./build/bin/whisper-cli \
-   --file ./samples/jfk.wav \
-   --model ./models/ggml-base.en.bin \
-   --vad \
-   --vad-model ./models/silero-v5.1.2-ggml.bin
-```
-
-### VAD Options
-
-* --vad-threshold: Threshold probability for speech detection. A probability
-for a speech segment/frame above this threshold will be considered as speech.
-
-* --vad-min-speech-duration-ms: Minimum speech duration in milliseconds. Speech
-segments shorter than this value will be discarded to filter out brief noise or
-false positives.
-
-* --vad-min-silence-duration-ms: Minimum silence duration in milliseconds. Silence
-periods must be at least this long to end a speech segment. Shorter silence
-periods will be ignored and included as part of the speech.
-
-* --vad-max-speech-duration-s: Maximum speech duration in seconds. Speech segments
-longer than this will be automatically split into multiple segments at silence
-points exceeding 98ms to prevent excessively long segments.
-
-* --vad-speech-pad-ms: Speech padding in milliseconds. Adds this amount of padding
-before and after each detected speech segment to avoid cutting off speech edges.
-
-* --vad-samples-overlap: Amount of audio to extend from each speech segment into
-the next one, in seconds (e.g., 0.10 = 100ms overlap). This ensures speech isn't
-cut off abruptly between segments when they're concatenated together.

-## Background
-
-SYCL is a higher-level programming model to improve programming productivity on various hardware accelerators—such as CPUs, GPUs, and FPGAs. It is a single-source embedded domain-specific language based on pure C++17.
-
-oneAPI is a specification that is open and standards-based, supporting multiple architecture types including but not limited to GPU, CPU, and FPGA. The spec has both direct programming and API-based programming paradigms.
-
-Intel uses the SYCL as direct programming language to support CPU, GPUs and FPGAs.
-
-To avoid  re-inventing the wheel, this code refers other code paths in llama.cpp (like OpenBLAS, cuBLAS, CLBlast). We use a open-source tool [SYCLomatic](https://github.com/oneapi-src/SYCLomatic) (Commercial release [Intel® DPC++ Compatibility Tool](https://www.intel.com/content/www/us/en/developer/tools/oneapi/dpc-compatibility-tool.html)) migrate to SYCL.
-
-The whisper.cpp for SYCL is used to support Intel GPUs.
-
-For Intel CPU, recommend to use whisper.cpp for X86 (Intel MKL build).

-### Voice Activity Detection (VAD) ###
-
-Support for Voice Activity Detection (VAD) can be enabled by setting `Whisper::Params`'s `vad` argument to `true` and specifying VAD model:
-
-```ruby
-Whisper::Params.new(
-  vad: true,
-  vad_model_path: "silero-v5.1.2",
-  # other arguments...
-)
-```
-
-When you pass the model name (`"silero-v5.1.2"`) or URI (`https://huggingface.co/ggml-org/whisper-vad/resolve/main/ggml-silero-v5.1.2.bin`), it will be downloaded automatically.
-Currently, "silero-v5.1.2" is registered as pre-converted model like ASR models. You also specify file path or URI of model.
-
-If you need configure VAD behavior, pass params for that:
-
-```ruby
-Whisper::Params.new(
-  vad: true,
-  vad_model_path: "silero-v5.1.2",
-  vad_params: Whisper::VAD::Params.new(
-    threshold: 1.0, # defaults to 0.5
-    min_speech_duration_ms: 500, # defaults to 250
-    min_silence_duration_ms: 200, # defaults to 100
-    max_speech_duration_s: 30000, # default is FLT_MAX,
-    speech_pad_ms: 50, # defaults to 30
-    samples_overlap: 0.5 # defaults to 0.1
-  ),
-  # other arguments...
-)
-```
-
-For details on VAD, see [whisper.cpp's README](https://github.com/ggml-org/whisper.cpp?tab=readme-ov-file#voice-activity-detection-vad).

-### Transcription ###
-
-By default, `Whisper::Context#transcribe` works in a single thread. You can make it work in parallel by passing `n_processors` option:
-
-```ruby

-Note that transcription occasionally might be low accuracy when it works in parallel.

-# whisper.cpp Node.js addon
+# addon

 This is an addon demo that can **perform whisper model reasoning in `node` and `electron` environments**, based on [cmake-js](https://github.com/cmake-js/cmake-js).
 It can be used as a reference for using the whisper.cpp project in other node projects.

-This addon now supports **Voice Activity Detection (VAD)** for improved transcription performance.
-
 ## Install

 ```shell
@ -28,88 +26,12 @@ For Electron addon and cmake-js options, you can see [cmake-js](https://github.c

 ## Run

-### Basic Usage
-
 ```shell
 cd examples/addon.node

 node index.js --language='language' --model='model-path' --fname_inp='file-path'
 ```

-### VAD (Voice Activity Detection) Usage
+Because this is a simple Demo, only the above parameters are set in the node environment.

-Run the VAD example with performance comparison:
-
-```shell
-node vad-example.js
-```
-
-## Voice Activity Detection (VAD) Support
-
-VAD can significantly improve transcription performance by only processing speech segments, which is especially beneficial for audio files with long periods of silence.
-
-### VAD Model Setup
-
-Before using VAD, download a VAD model:
-
-```shell
-# From the whisper.cpp root directory
-./models/download-vad-model.sh silero-v5.1.2
-```
-
-### VAD Parameters
-
-All VAD parameters are optional and have sensible defaults:
-
- `vad`: Enable VAD (default: false)
- `vad_model`: Path to VAD model file (required when VAD enabled)
- `vad_threshold`: Speech detection threshold 0.0-1.0 (default: 0.5)
- `vad_min_speech_duration_ms`: Min speech duration in ms (default: 250)
- `vad_min_silence_duration_ms`: Min silence duration in ms (default: 100)
- `vad_max_speech_duration_s`: Max speech duration in seconds (default: FLT_MAX)
- `vad_speech_pad_ms`: Speech padding in ms (default: 30)
- `vad_samples_overlap`: Sample overlap 0.0-1.0 (default: 0.1)
-
-### JavaScript API Example
-
-```javascript
-const path = require("path");
-const { whisper } = require(path.join(__dirname, "../../build/Release/addon.node"));
-const { promisify } = require("util");
-
-const whisperAsync = promisify(whisper);
-
-// With VAD enabled
-const vadParams = {
-  language: "en",
-  model: path.join(__dirname, "../../models/ggml-base.en.bin"),
-  fname_inp: path.join(__dirname, "../../samples/jfk.wav"),
-  vad: true,
-  vad_model: path.join(__dirname, "../../models/ggml-silero-v5.1.2.bin"),
-  vad_threshold: 0.5,
-  progress_callback: (progress) => console.log(`Progress: ${progress}%`)
-};
-
-whisperAsync(vadParams).then(result => console.log(result));
-```
-
-## Supported Parameters
-
-Both traditional whisper.cpp parameters and new VAD parameters are supported:
-
- `language`: Language code (e.g., "en", "es", "fr")
- `model`: Path to whisper model file
- `fname_inp`: Path to input audio file
- `use_gpu`: Enable GPU acceleration (default: true)
- `flash_attn`: Enable flash attention (default: false)
- `no_prints`: Disable console output (default: false)
- `no_timestamps`: Disable timestamps (default: false)
- `detect_language`: Auto-detect language (default: false)
- `audio_ctx`: Audio context size (default: 0)
- `max_len`: Maximum segment length (default: 0)
- `max_context`: Maximum context size (default: -1)
- `prompt`: Initial prompt for decoder
- `comma_in_time`: Use comma in timestamps (default: true)
- `print_progress`: Print progress info (default: false)
- `progress_callback`: Progress callback function
- VAD parameters (see above section)
+Other parameters can also be specified in the node environment.

-## Load testing with k6
-
-> **Note:** Install [k6](https://k6.io/docs/get-started/installation/) before running the benchmark script.
-
-You can benchmark the Whisper server using the provided bench.js script with [k6](https://k6.io/). This script sends concurrent multipart requests to the /inference endpoint and is fully configurable via environment variables.
-
-**Example usage:**
-
-```
-k6 run bench.js \
-  --env FILE_PATH=/absolute/path/to/samples/jfk.wav \
-  --env BASE_URL=http://127.0.0.1:8080 \
-  --env ENDPOINT=/inference \
-  --env CONCURRENCY=4 \
-  --env TEMPERATURE=0.0 \
-  --env TEMPERATURE_INC=0.2 \
-  --env RESPONSE_FORMAT=json
-```
-
-**Environment variables:**
- `FILE_PATH`: Path to the audio file to send (must be absolute or relative to the k6 working directory)
- `BASE_URL`: Server base URL (default: `http://127.0.0.1:8080`)
- `ENDPOINT`: API endpoint (default: `/inference`)
- `CONCURRENCY`: Number of concurrent requests (default: 4)
- `TEMPERATURE`: Decoding temperature (default: 0.0)
- `TEMPERATURE_INC`: Temperature increment (default: 0.2)
- `RESPONSE_FORMAT`: Response format (default: `json`)
-
-**Note:**
- The server must be running and accessible at the specified `BASE_URL` and `ENDPOINT`.
- The script is located in the same directory as this README: `bench.js`.

shalinib-ibm	0630539c8a	ggml : Enable MMA for BF16 in llamafile_sgemm (llama/13148) This patch upstreams llamafile's cpu matrix multiplication kernels for ppc64le using MMA builtins for BF16 data type. This change results in 9x - 40x gains in total speed S t/s (ie all tokens/total time), across various batch sizes tested using llama-batched-bench benchmark. The patch is tested with Meta-Lllama-3-8B, and Mistral-7B models (BF16 models generated by using llama-quantize from corresponding FP32 models) on an IBM POWER10 machine.

Jesse Gross	37ac0264ef	ggml: Don't assert fail when tensor data changes (llama/13222) The following scenario will cause an assertion failure in the graph allocator: - Build and allocate a graph containing a tensor with a non-NULL data pointer - Build and allocate a new graph where that data is NULL Result: ggml-alloc.c:819: GGML_ASSERT(talloc->buffer_id >= 0) failed This happens during revalidation because we think that memory should have been previously allocated based on the current graph but in reality the previous graph was different. In this situation, we should do a full reallocation pass.	2025-05-07 13:17:41 +03:00

Jeff Bolz	cde0e50536	vulkan: Add bfloat16 support (llama/12554) * vulkan: Add bfloat16 support This adds bfloat16 matrix multiply support based on VK_KHR_shader_bfloat16. The extension is required for coopmat multiply support, but matrix-vector multiply trivially promotes bf16 to fp32 and doesn't require the extension. The copy/get_rows shaders also don't require the extension. It's probably possible to fall back to non-coopmat and promote to fp32 when the extension isn't supported, but this change doesn't do that. The coopmat support also requires a glslc that supports the extension, which currently requires a custom build. * vulkan: Support bf16 tensors without the bf16 extension or coopmat support Compile a variant of the scalar mul_mm shader that will promote the bf16 values to float, and use that when either the bf16 extension or the coopmat extensions aren't available. * vulkan: bfloat16 fixes (really works without bfloat16 support now) * vulkan: fix spirv-val failure and reenable -O	2025-05-07 13:17:41 +03:00
