Proposed change

This is updated documentation for the change proposed here.

The existing implementation has a hard-coded 10s timeout when waiting for the generated speech from Google Cloud TTS.
Because of that, the integration fails (error "400 Request contains an invalid argument") when you try to generate outputs larger than roughly 600-800 characters, since it would take longer than that for Google Cloud TTS to return a response. I've been hitting this issue constantly when trying to announce long responses coming from my LLM, for example.

The proposed change makes both STT and TTS Timeout configurable in the UI along with the existing model options. The default value is set at 10 seconds (same as the existing implementation), but now users can increase it if needed to generate longer output. The tests have been updated, too.

This updates the documentation to add the timeout option (used by both STT and TTS).

Type of change

  • Spelling, grammar or other readability improvements (current branch).
  • Adjusted missing or incorrect information in the current documentation (current branch).
  • Added documentation for a new integration I'm adding to Home Assistant (next branch).
  • Added documentation for a new feature I'm adding to Home Assistant (next branch).
  • Removed stale or deprecated documentation.

Additional information

Checklist

  • This PR uses the correct branch, based on one of the following:
    • I made a change to the existing documentation and used the current branch.
    • I made a change that is related to an upcoming version of Home Assistant and used the next branch.
  • The documentation follows the Home Assistant documentation standards.

Summary by CodeRabbit

  • New Features
    • Added a configurable timeout option for Google Cloud text-to-speech integration.
    • Users can now adjust the waiting time for TTS response generation (default: 10 seconds), with a range from 1 to 60 seconds.

📝 Walkthrough

Walkthrough

The pull request introduces a new configuration option timeout to the Google Cloud text-to-speech integration documentation. This option specifies the time in seconds to wait for the STT/TTS response generation, with a default value set to 10 seconds. The addition includes a description indicating that the default timeout is sufficient in most cases. The timeout parameter is marked as not required, has a type of integer, and includes a selector that restricts the value between 1 and 60 seconds.

Changes

File Change Summary
source/_integrations/google_cloud.markdown Added new configuration option timeout with type integer, default value of 10 seconds, and description for STT/TTS response generation timeout.

The sequence diagram illustrates how the new timeout configuration allows users to set a custom timeout when requesting text-to-speech generation from Google Cloud, with Home Assistant managing the request based on the specified duration.

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

🛠️ Refactor suggestion

Enhance the configuration documentation for better clarity and completeness.

The documentation for the new tts_timeout option needs improvements in several areas:

  1. Grammar and clarity
  2. Missing important context
  3. Configuration details

Apply this diff to improve the documentation:

 tts_timeout:
-  description: "Time in seconds to wait for the TTS response generation. Increasing this value will allow to generate longer audio files from Google Cloud TTS"
+  description: "Time in seconds to wait for the TTS response generation. The default timeout of 10 seconds is sufficient for most text (up to 600-800 characters). For longer text, increase this value to allow more time for audio file generation. Configurable through the UI."
   required: false
   type: int
   default: 10
+  selector:
+    number:
+      min: 1
+      max: 120
+      unit_of_measurement: seconds

The changes:

  • Fix grammar in description
  • Add context about character limits
  • Add UI configuration mention
  • Add selector with reasonable min/max values
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
