FFmpeg VAD Streaming

Streaming inference from arbitrary source (FFmpeg input) to DeepSpeech, using VAD (voice activity detection). A fairly simple example demonstrating the DeepSpeech streaming API in Node.js.

This example was successfully tested with a mobile phone streaming a live feed to a RTMP server (nginx-rtmp), which then could be used by this script for near real time speech recognition.

Installation

npm install

Moreover FFmpeg must be installed:

sudo apt-get install ffmpeg

Usage

Here is an example for a local audio file:

node ./index.js --audio <AUDIO_FILE> --model $HOME/models/output_graph.pbmm --alphabet $HOME/models/alphabet.txt

Here is an example for a remote RTMP-Stream:

node ./index.js  --audio rtmp://<IP>:1935/live/teststream --model $HOME/models/output_graph.pbmm --alphabet $HOME/models/alphabet.txt
