# Google Speech

The `robomotion googlespeech` CLI connects to Google Cloud Speech APIs for audio transcription and speech synthesis. It transcribes audio files to text and converts text to speech audio files.

## When to use
- Transcribe audio files to text in multiple languages
- Convert text to speech audio files

## Prerequisites
- `robomotion` CLI installed
- Package installed: `robomotion install googlespeech`
- Google Cloud Speech API credentials configured via Robomotion vault

## IMPORTANT: Session Mode Required for Multi-Step Operations
Each CLI command runs as a **separate process** — connection IDs from `connect` do NOT persist across calls.
You MUST use `--session` on `connect` and pass `--session-id` to all subsequent commands.

## Workflow
1. Install (once): `robomotion install googlespeech`
2. Connect with session:
   ```
   robomotion googlespeech connect --session --output json
   # → {"outClientId":"<client-id>","session_id":"<session-id>"}
   ```
3. Use the returned `client-id` and `session-id` in all subsequent commands:
   ```
   robomotion googlespeech speech_to_text --client-id "<client-id>" --audio-file <path> --session-id "<session-id>" --output json
   ```
4. Disconnect when done:
   ```
   robomotion googlespeech disconnect --client-id "<client-id>" --session-id "<session-id>" --output json
   ```

**Always** append `--output json` to get structured JSON results.
