About

This library detects silence segment from speech signal.

Installation

$ pip install pysaten

Usage

Command line

The audio file is exported as 24-bit PCM at 48 kHz, mono.

$ pysaten_trim input.wav trimmed.wav

Python

import pysaten

# y: Target signal, obtained using libraries such as librosa or soundfile.
# sr: Sampling rate.

# Get trimmed signal for the speech segment only.
y_trimmed = pysaten.trim(y, sr)

# If you trim manually or want to get start/end time...
start_s, end_s = pysaten.vsed(y, sr)
y_trimmed = y[int(start_s * sr) : int(end_s * sr)]
# start_s: Start of speech segment. Unit is seconds.
# end_s: End of speech segment. Unit is seconds.

For development (Linux only)
