Quick Start

Setup

1. Install Python 3 .

2. Install the pvcheetah Python package using PIP:

pip3 install pvcheetah

Usage

Create an instance of the engine and transcribe audio:

import pvcheetah

cheetah = pvcheetah.create(access_key='${ACCESS_KEY}')

def get_next_audio_frame():
    pass

while True:
    partial_transcript, is_endpoint = cheetah.process(get_next_audio_frame())
    if is_endpoint:
        final_transcript = cheetah.flush()

Free resources used by Cheetah:

cheetah.delete()

Demo

For the Cheetah Python SDK, we offer demo applications that demonstrate how to use the Speech-to-Text engine on real-time audio streams (i.e. microphone input).

Setup

Install the pvcheetahdemo Python package using PIP:

pip3 install pvcheetahdemo

This package installs command-line utilities for the Cheetah Python demos.

Usage

Use the --help flag to see the usage options for the demo:

cheetah_demo_mic --help

Run the following command to start transcribing microphone input:

cheetah_demo_mic --access_key ${ACCESS_KEY}
