Octopus Speech-to-Index engine demo.

Project description

Octopus Speech-to-Index engine

Made in Vancouver, Canada by Picovoice

This package contains commandline program for indexing and searching inside audio files using Octopus Speech-to-Index engine.


Octopus is Picovoice's Speech-to-Index engine. It directly indexes speech without relying on a text representation.


  • Python 3
  • Runs on Linux (x86_64), macOS (x86_64, arm64), Windows (x86_64).


Octopus requires a valid Picovoice AccessKey at initialization. AccessKey acts as your credentials when using Octopus 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.


sudo pip3 install pvoctopusdemo


This demo allows testing Octopus interactively through commandline. It accepts MP3, WAV, FLAC, and OPUS audio files with sample rates higher than 16kHz. The following command processes all files in the space-separated {AUDIO_PATHS} list:

octopus_demo  --access_key {AccessKey} --audio_paths ${AUDIO_PATHS}

where {AccessKey} is an AccessKey which should be obtained from Picovoice Console.

After processing audio files, you are asked for a search phrase:

Enter search phrase (Ctrl+c to exit):

The search phrase can have several words separated by space, but each word should only consist of alphabetic characters. As shown in the prompt above, press Ctrl and C keys at the same time to exit the program.
