Silero VAD - pre-trained enterprise-grade Voice Activity Detector

This directory provides VAD models on CPU/GPU.

VAD Interface

For vad interface please see .

Create Handdle

PPSHandle_t PPSVadCreateInstance(const char* conf_path);

Destroy Handdle

int PPSVadDestroyInstance(PPSHandle_t instance);

Reset Vad State

int PPSVadReset(PPSHandle_t instance);

Reset Vad state before processing next wav.

Get Chunk Size

int PPSVadChunkSizeSamples(PPSHandle_t instance);

This API will return chunk size in sample unit. When do forward, we need feed chunk size samples, except last chunk.

Vad Forward

PPSVadState_t PPSVadFeedForward(PPSHandle_t instance,
                                float* chunk,
                                int num_element);

Vad has below states:

typedef enum {
    PPS_VAD_ILLEGAL = 0,  // error
    PPS_VAD_SIL,          // silence
    PPS_VAD_START,        // start speech
    PPS_VAD_SPEECH,       // in speech
    PPS_VAD_END,          // end speech
    PPS_VAD_NUMSTATES,    // number of states
} PPSVadState_t;

If PPSVadFeedForward occur an error will return PPS_VAD_ILLEGAL state.

Linux

Build Runtime

# cd /path/to/paddlespeech/runtime
cmake -B build -DBUILD_SHARED_LIBS=OFF -DWITH_ASR=OFF -DWITH_CLS=OFF -DWITH_VAD=ON
cmake --build build

Since VAD using FastDeploy runtime, if you have another FastDeploy Library, you can using this command to build:

# cd /path/to/paddlespeech/runtime
cmake -B build -DBUILD_SHARED_LIBS=OFF -DWITH_ASR=OFF -DWITH_CLS=OFF -DWITH_VAD=ON -DFASTDEPLOY_INSTALL_DIR=/workspace//paddle/FastDeploy/build/Linux/x86_64/install
cmake --build build

DFASTDEPLOY_INSTALL_DIR is the directory of FastDeploy Library.

Run Demo

After building success, we can do this to run demo under this example dir:

bash run.sh

The output like these:
