Google

Status: implemented for LLM, STT, and TTS.

Use Google when you need Gemini-backed LLM behavior or Google speech services through the source-backed adapter package.

Source-backed capabilities

• LLM: adapter/google/llm.go
• STT: adapter/google/stt.go
• TTS: adapter/google/tts.go

Constructors include NewGoogleLLM, NewGoogleSTT, and NewGoogleTTS.

Credentials

The LLM path reads API-key style configuration. STT and TTS use Google credentials file configuration through constructor arguments or app configuration such as RTP_AGENT_GOOGLE_CREDENTIALS_FILE and GOOGLE_APPLICATION_CREDENTIALS.

Do not document Google realtime or avatar support unless matching source files are added.
