AccessKey

AccessKey is your authentication and authorization token for deploying Picovoice SDKs, including Cheetah. Anyone who is using Picovoice needs to have a valid AccessKey. You must keep your AccessKey secret. You would need internet connectivity to validate your AccessKey with Picovoice license servers even though the voice recognition is running 100% offline.

AccessKey also verifies that your usage is within the limits of your account. Everyone who signs up for Picovoice Console receives the Free Tier usage rights described here. If you wish to increase your limits, you can purchase a subscription plan.

Usage

File Demo

Run the following in the terminal:

cheetah_demo_file --access_key ${ACCESS_KEY} --input_audio_file_path ${AUIDO_PATH}

Replace ${ACCESS_KEY} with yours obtained from Picovoice Console and ${AUDIO_PATH} with a path to an audio file you wish to transcribe.

Microphone Demo

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

cheetah_demo_mic --access_key ${ACCESS_KEY}

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