Google Speech

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.
