The Google Cloud integration allows you to use [Google Cloud Platform](https://cloud.google.com/) APIs and integrate them into Home Assistant.

{% include integrations/config_flow.md %}

## Obtaining service account file

1. Visit [Cloud Resource Manager](https://console.cloud.google.com/cloud-resource-manager).
2. Click `CREATE PROJECT` button at the top.
3. Specify convenient `Project name` and click `CREATE` button.
4. [Make sure that billing is enabled for your Google Cloud Platform project](https://cloud.google.com/billing/docs/how-to/modify-project).
5. Enable needed Cloud API visiting one of the links below or [APIs library](https://console.cloud.google.com/apis/library), selecting your `Project` from the dropdown list and clicking the `Continue` button:


    - [Text-to-speech](https://console.cloud.google.com/flows/enableapi?apiid=texttospeech.googleapis.com)
    - [Speech-to-text](https://console.cloud.google.com/flows/enableapi?apiid=speech.googleapis.com)
6. Set up authentication:

    1. Visit [this link](https://console.cloud.google.com/apis/credentials/serviceaccountkey)
    2. From the toolbar above the `Service account` list, select `Create service account`.
    3. In the `Service account name` field, enter any name.

    If you are requesting a text-to-speech API key:

    4. Don't select a value from the Role list. **No role is required to access this service**.
    5. Click `Create`. If a note appears, warning that this service account has no role, you may ignore that.
    6. Return to the `Service account` list page and click on the service account you created in step 5 to see the details for this service account.
    7. Choose the `Keys` tab within the details view for this service account.
    8. In the `Add Key` dropdown, select `Create New Key`.
    9. Specify a `JSON` key type  and click `Create`.
    10. A `[serviceaccountname].json` file will download to your browser.
    11. Upload this file when asked in the integration setup.


## Google Cloud text-to-speech

[Google Cloud text-to-speech](https://cloud.google.com/text-to-speech/) converts text into human-like speech in [380+ voices across 50+ languages and variants](https://cloud.google.com/text-to-speech/docs/voices). It applies groundbreaking research in speech synthesis and Google's powerful neural networks to deliver high-fidelity audio. With this easy-to-use API, you can create lifelike interactions with your users that transform customer service, device interaction, and other applications.

### Pricing

The Cloud text-to-speech API is priced monthly based on the number of characters to synthesize into audio sent to the service. For up-to-date pricing, see [here](https://cloud.google.com/text-to-speech/pricing).

### Text-to-speech configuration

Below settings can be configured in the options of the integration and in the `options` parameter of the `tts.speak` service.

{% configuration %}
language:
  description: "Default language of the voice, e.g.,  `en-US`. Supported languages, genders and voices listed [here](https://cloud.google.com/text-to-speech/docs/voices). Also there are extra not documented but supported languages (see dropdown [here](https://cloud.google.com/text-to-speech/#streaming_demo_section))."
  required: false
  type: string
  default: en-US
gender:
  description: "Default gender of the voice, e.g.,  `male`. Supported languages, genders and voices listed [here](https://cloud.google.com/text-to-speech/docs/voices)."
  required: false
  type: string
  default: neutral
voice:
  description: "Default voice name, e.g.,  `en-US-Wavenet-F`. Supported languages, genders and voices listed [here](https://cloud.google.com/text-to-speech/docs/voices). **Important! This parameter will override `language` and `gender` parameters if set**."
  required: false
  type: string
encoding:
  description: "Default audio encoder. Supported encodings are `ogg_opus`, `mp3` and `linear16`."
  required: false
  type: string
  default: mp3
speed:
  description: "Default rate/speed of the voice, in the range [0.25, 4.0]. 1.0 is the normal native speed supported by the specific voice. 2.0 is twice as fast, and 0.5 is half as fast. If unset(0.0), defaults to the native 1.0 speed."
  required: false
  type: float
  default: 1.0
pitch:
  description: "Default pitch of the voice, in the range [-20.0, 20.0]. 20 means increase of 20 semitones from the original pitch. -20 means decrease of 20 semitones from the original pitch."
  required: false
  type: float
  default: 0.0
gain:
  description: "Default volume gain (in dB) of the voice, in the range [-96.0, 16.0]. If unset, or set to a value of 0.0 (dB), will play at normal native signal amplitude. A value of -6.0 (dB) will play at approximately half the amplitude of the normal native signal amplitude. A value of +6.0 (dB) will play at approximately twice the amplitude of the normal native signal amplitude. Strongly recommend not to exceed +10 (dB) as there's usually no effective increase in loudness for any value greater than that."
  required: false
  type: float
  default: 0.0
profiles:
  description: "An identifier which selects 'audio effects' profiles that are applied on (post synthesized) text-to-speech. Effects are applied on top of each other in the order they are given. Supported profile ids listed [here](https://cloud.google.com/text-to-speech/docs/audio-profiles)."
  required: false
  type: list
  default: "[]"
text_type:
  description: "Default text type. Supported text types are `text` and `ssml`. Read more on what is that and how to use SSML [here](https://cloud.google.com/text-to-speech/docs/ssml)."
  required: false
  type: string
  default: "text"
{% endconfiguration %}

### Action speak

The `tts.speak` action is the modern way to use Google Cloud TTS action. Add the `speak` action, select the entity for your Google Cloud TTS, select the media player entity or group to send the TTS audio to, and enter the message to speak.

For more options about `speak`, see the Speak section on the main [TTS](/integrations/tts/#action-speak) building block page.

A `tts.speak` service call can look like:

```yaml
service: tts.speak
target:
  entity_id: tts.google_cloud
data:
  cache: true
  media_player_entity_id: media_player.living_room_display
  message: this is a test
  language: en-US
  options:
    gender: male
    voice: en-US-Wavenet-F
    encoding: linear16
    speed: 0.9
    pitch: -2.5
    gain: -5.0
    text_type: ssml
    profiles:
      - telephony-class-application
      - wearable-class-device
```

## Action say (legacy)

The `tts.google_cloud_say` action can be used when configuring the legacy `google_cloud` text-to-speech platform in `configuration.yaml`. We recommend new users to instead set up the integration in the UI and use the `tts.speak` action with the corresponding Google Cloud text-to-speech entity as target. If you are an existing user of `tts.google_cloud_say`, you can still use it but don't remove the legacy `google_cloud` text-to-speech platform in `configuration.yaml`. If you remove it, you will have to manually migrate to `tts.speak`.

## Google Cloud speech-to-text

[Google Cloud speech-to-text](https://cloud.google.com/speech-to-text) converts audio into text transcriptions for [125 languages and variants](https://cloud.google.com/speech-to-text/docs/speech-to-text-supported-languages).

### Pricing

Speech-to-text is priced based on the amount of audio successfully processed by the service each month, measured in increments of one second. For up-to-date pricing, see [here](https://cloud.google.com/speech-to-text/pricing) under the Speech-to-text v1 API.

### Speech-to-text configuration

{% configuration %}
stt_model:
  description: "One of the transcription models [here](https://cloud.google.com/speech-to-text/docs/transcription-model). Defaults to `latest_short` because this is the recommended one. If you get: `400 Invalid recognition 'config': The requested model is currently not supported for language : <language code>` try changing this to the legacy `command_and_search`."
  required: false
  type: string
{% endconfiguration %}
