webrtcVadBufferSize: How many audio samples to pass to the first-pass VAD filter.0 is least aggressive, and 3 is most aggressive. webrtcVadLevel: Aggressiveness for the first-pass VAD filter.sileroVadSpeakingThreshold: Probability threshold for silence to transition to speech.sileroVadSilenceThreshold: Probability threshold for speech to transition to silence.sileroVadRateLimit: Rate limit, in frames, for how frequently to call the VAD.sileroVadBufferSize: How many audio samples to pass to the VAD.samplesPerFrame: How many audio samples to be included in each frame from the microphone.
onChunkEnd: Callback to be executed when speech ends.onAudio: Callback to be executed when any audio comes in.onChunkStart: Callback to be executed when speech starts.leadingBufferFrames: How many frames of audio to keep in a buffer that's included in onChunkStart.consecutiveFramesForSpeaking: How many frames of audio must be speech before onChunkStart is fired.consecutiveFramesForSilence: How many frames of audio must be silent before onChunkEnd is fired.onChunkStart is called when a chunk of speech begins, and onChunkEnd is called when speech ends. onAudio is called when any audio comes in from the microphone. When you start recording, you can register various callbacks. See below for the various options you can supply to each. This library uses two voice activity detection mechanisms: a fast first pass (the WebRTC VAD), and a slightly slower, but much more accurate, second pass (the Silero VAD). If you're using this library with Electron, you should probably use electron-rebuild.
To install speech-recorder, run: yarn add speech-recorder Speech-recorder has been tested on Windows 10, macOS 10.14+, and Ubuntu 18.04+ (and may work on other platforms as well).
Serenade enables you to write code through natural speech, rather than typing. This module is used for speech recognition in Serenade. Using speech-recorder, you can also get only the audio that corresponds to someone speaking. Speech-recorder is a cross-platform, native node.js addon for getting a stream of audio from a device's microphone.
