Installation

pip3 install pvbat

AccessKey

Bat requires a valid Picovoice AccessKey at initialization. AccessKey acts as your credentials when using Bat SDKs. You can get your AccessKey for free. Make sure to keep your AccessKey secret. Signup or Login to Picovoice Console to get your AccessKey.

Usage

Create an instance of the engine and detect the spoken language from an audio stream.

import pvbat

handle = pvbat.create(access_key='${ACCESS_KEY}')

def get_next_audio_frame():
    pass

while True:
    language_scores = handle.process(get_next_audio_frame())
    if language_scores:
        print(language_scores)

Replace ${ACCESS_KEY} with yours obtained from Picovoice Console. When done be sure to explicitly release the resources using handle.delete().

Demos

pvbatdemo provides command-line utilities for processing audio using Bat.
