About

This library detects silence segment from speech signal.

(alt: Image of Voice Start-End Detection)

Installation

pip install pysaten

Usage

Command line

pysaten_trim input.wav trimmed.wav

Python

import pysaten

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

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

# If you trim manually or want to get start/end time...
start_sec, end_sec = pysaten.vsed(y, sr)
y_trimmed = y[int(start_sec * sr) : int(end_sec * sr)]

For development

git clone https://gitlab.com/f-matano44/pysaten.git
