Usage

Microphone Demo

The mic demo takes audio input from a microphone and outputs the language detection scores to the terminal.

You need a working microphone connected to your machine for this demo. Run the following in the terminal:

bat_demo_mic --access_key ${ACCESS_KEY}

Replace ${ACCESS_KEY} with yours obtained from Picovoice Console.

File Demo

The file demo takes audio input from a series of .wav files and prints the language detection scores to the terminal. Each set of scores is tagged with the timestamp in seconds for the corresponding audio file.

Run the following in the terminal:

bat_demo_file --access_key ${ACCESS_KEY} --wav_paths ${WAV_PATH}

Replace ${ACCESS_KEY} with yours obtained from Picovoice Console and ${WAV_PATH} with a path to a compatible (single-channel, 16 kHz, 16-bit PCM) wav file you wish to process.
