Format: wav`;

API base URL: ${streamV1}
Endpoint: /audio/speech
Model: tts-1
Voice: ${voice}
Response format: wav
Requirement: the app must start playback while the HTTP response is still arriving.
Current 8023 streaming service ignores per-request instruct/style text.

Streaming through TTS Voice Creator routing:
API base URL: ${proxyV1}
Voice: default or another incoming route voice
Routing tab: set Backend = Streaming for the matching rule
Response format: wav
Avoid before/after sounds for true streaming; route sounds and MP3 require buffering.

SillyTavern note:
Use OpenAI-compatible TTS if your extension supports progressive audio responses. If it waits for the whole file before playing, streaming works technically but will feel like buffered TTS.`;
