Bridges standardize how you call any STT or TTS model. Same URL shape, every provider. Switching models means changing the URL — nothing in your code.

​
Swap models without touching your code

Every endpoint follows the same structure: 
/v1/bridges/{bridge}/{stt|tts}/{provider}/{model}:{variant}
Switching providers is a one-line change: 
# Deepgram Nova 3
wss://api.slng.ai/v1/bridges/unmute/stt/deepgram/nova:3

# Different provider — only the URL changes
wss://api.slng.ai/v1/bridges/unmute/stt/slng/openai/whisper:large-v3
