:description: Instructions for setting up a Voice Assistant in ESPHome.
|
|
:image: voice-assistant.svg
|
|
|
|
ESPHome devices with a microphone are able to stream the audio to Home Assistant and be processed there by `assist <https://www.home-assistant.io/voice_control/>`__.
|
|
|
|
.. note::
|
|
|
|
Voice Assistant requires Home Assistant 2023.5 or later.
|
|
|
|
.. warning::
|
|
|
|
Audio and voice components consume a significant amount of resources (RAM, CPU) on the device.
|
|
|
|
**Crashes are likely to occur** if you include too many additional components in your device's
|
|
configuration. In particular, Bluetooth/BLE components are known to cause issues when used in
|
|
combination with Voice Assistant and/or other audio components.
|
|
|
|
Configuration:
|
|
--------------
|
|

|
|
- **speaker** (*Optional*, :ref:`config-id`): The :doc:`speaker </components/speaker/index>` to use to output the response.
|
|
Cannot be used with ``media_player`` below.
|
|
- **media_player** (*Optional*, :ref:`config-id`): The :doc:`media_player </components/media_player/index>` to use
|
|
to output the response. Cannot be used with ``speaker`` above.
|
|
- **use_wake_word** (*Optional*, boolean): Enable wake word on the assist pipeline. Defaults to ``false``.
|
|
- **on_intent_start** (*Optional*, :ref:`Automation <automation>`): An automation to perform when intent processing starts.
|
|
- **on_intent_end** (*Optional*, :ref:`Automation <automation>`): An automation to perform when intent processing ends.
|
|
- **on_listening** (*Optional*, :ref:`Automation <automation>`): An automation to
|
|
perform when the voice assistant microphone starts listening.
|
|
- **on_start** (*Optional*, :ref:`Automation <automation>`): An automation to
|
|
perform when the assist pipeline is started.
|
|
- **on_wake_word_detected** (*Optional*, :ref:`Automation <automation>`): An automation
|
|
to perform when the assist pipeline has detected a wake word.
|
|
- **on_end** (*Optional*, :ref:`Automation <automation>`): An automation to perform
|
|
when the voice assistant is finished all tasks.
|
|
- **on_stt_end** (*Optional*, :ref:`Automation <automation>`): An automation to perform
|
|
when the voice assistant has finished speech-to-text. The resulting text is
|
|
available to automations as the variable ``x``.
|
|
- **on_stt_vad_start** (*Optional*, :ref:`Automation <automation>`): An automation to perform when voice activity
|
|
detection starts speech-to-text processing.
|
|
- **on_stt_vad_end** (*Optional*, :ref:`Automation <automation>`): An automation to perform when voice activity
|
|
detection ends speech-to-text processing.
|
|
- **on_tts_start** (*Optional*, :ref:`Automation <automation>`): An automation to perform
|
|
when the voice assistant has started text-to-speech. The text to be spoken is
|
|
available to automations as the variable ``x``.
|
|
- **on_tts_end** (*Optional*, :ref:`Automation <automation>`): An automation to perform
|
|
when the voice assistant has finished text-to-speech. A URL containing the audio response
|
|
is available to automations as the variable ``x``.
|
|
- **on_tts_stream_start** (*Optional*, :ref:`Automation <automation>`): An automation to perform when audio stream
|
|
(voice response) playback starts. Requires ``speaker`` to be configured.
|
|
- **on_tts_stream_end** (*Optional*, :ref:`Automation <automation>`): An automation to perform when audio stream
|
|
(voice response) playback ends. Requires ``speaker`` to be configured.
|
|
- **on_idle** (*Optional*, :ref:`Automation <automation>`): An automation to perform
|
|
when the voice assistant is idle (no other actions/states are in progress).
|
|
- **on_error** (*Optional*, :ref:`Automation <automation>`): An automation to perform
|
|
when the voice assistant has encountered an error. The error code and message are available to
|
|
automations as the variables ``code`` and ``message``.
|
|
|
|
- **on_client_connected** (*Optional*, :ref:`Automation <automation>`): An automation to perform
|
|
when Home Assistant has connected and is waiting for Voice Assistant commands.
|
|
- **on_client_disconnected** (*Optional*, :ref:`Automation <automation>`): An automation to perform
|
|
when Home Assistant disconnects from the Voice Assistant.
|
|
|
|
- **noise_suppression_level** (*Optional*, integer): The noise suppression level to apply to the assist pipeline.
|
|
Between 0 and 4 inclusive. Defaults to 0 (disabled).
|
|
- **auto_gain** (*Optional*, dBFS): Auto gain level to apply to the assist pipeline.
|
|
Between 0dBFS and 31dBFS inclusive. Defaults to 0 (disabled).
|
|
- **volume_multiplier** (*Optional*, float): Volume multiplier to apply to the assist pipeline.
|
|

Voice Assistant Actions
|
|
-----------------------
|
|
|
|
The following actions are available for use in automations:
|
|
|
|
``voice_assistant.start``
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^

Listens for one voice command then stops.
|
|
|
|
Configuration variables:
|
|

|
|
|
|
Call ``voice_assistant.stop`` to signal the end of the voice command if ``silence_detection`` is set to ``false``.
|
|
|
|
|
|
``voice_assistant.start_continuous``
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|

|
|
the response audio has finished playing. Some errors will stop the cycle.
|
|
Call ``voice_assistant.stop`` to stop the cycle.
