jarvis-ui 2.3

Jarvis UI to perform voice commands via API calls

Deployments

Jarvis UI

Connects to Jarvis running in the backend to process request and response via API calls.

Kick off

Install

python -m pip install jarvis-ui

Initiate

import jarvis_ui


if __name__ == '__main__':
    jarvis_ui.start()

Environment Variables

Env vars are loaded from a .env file and validated using pydantic

To use custom .env files

If the filename is anything other than .env, set the filename as an env var env_file before importing jarvis_ui

import os
os.environ['env_file'] = "jarvis_ui.env"

import jarvis_ui

if __name__ == '__main__':
    jarvis_ui.start()

Mandatory

• REQUEST_URL: URL to which the API call has to be made. Can be localhost or a tunneled URL behind a reverse proxy/CDN.
• TOKEN: Authentication token.

Optional

• HEART_BEAT: Defaults to None - Interval in seconds to trigger background healthcheck on the server with automatic restart
• DEBUG: Defaults to False - Enable debug level logging
  
  
• SPEECH_TIMEOUT: Defaults to 0 for macOS, 10 for Windows - Timeout for speech synthesis
  
  
• NATIVE_AUDIO: Defaults to False - If set to True, the response is generated in the server's default voice
• WAKE_WORDS: Defaults to jarvis (Defaults to alexa in macOS older than 10.14) - Wake words to initiate Jarvis
• SENSITIVITY: Defaults to 0.5 - Sensitivity of wake word detection
  
  
• MICROPHONE_INDEX: Defaults to None - Use peripherals.py to get the index values
• VOICE_NAME: Defaults to the author's favorite per the OS. Name of the voice supported by the OperatingSystem
• VOICE_RATE: Defaults to the value in py3-tts module - Speed/rate at which the text should be spoken
• VOICE_PITCH: Defaults to the value in py3-tts module - Currently available only for Linux OS
  
  
• LISTENER_TIMEOUT: Defaults to 2 - Timeout for listener once wake word is detected - Awaits for a speech to begin until this limit
• LISTENER_PHRASE_LIMIT: Defaults to 5 - Timeout for phrase once listener is activated - Listener will be deactivated after this limit
• RECOGNIZER_SETTINGS: JSON object of customized speech recognition settings.

Custom settings for speech recognition

The default values for RECOGNIZER_SETTINGS are customized according to the author's voice pitch. Please use test_listener.py to figure out the suitable values in a trial and error method.

Sample settings (formatted as JSON object)

RECOGNIZER_SETTINGS: '{"energy_threshold": 1100, "dynamic_energy_threshold": false, "pause_threshold": 1, "phrase_threshold": 0.1}'

Description

• energy_threshold: Minimum audio energy to consider for recording. Greater the value, louder the voice should be.
• dynamic_energy_threshold: Change considerable audio energy_threshold dynamically.
• pause_threshold: Seconds of non-speaking audio before a phrase is considered complete.
• phrase_threshold: Minimum seconds of speaking audio before it can be considered a phrase - values below this are ignored. This helps to filter out clicks and pops.
• non_speaking_duration: Seconds of non-speaking audio to keep on both sides of the recording.
