# ElevenLabs Performance Tuning ## Overview Optimize ElevenLabs TTS latency and throughput through model selection, streaming strategies, audio format tuning, and caching. Latency ranges from ~75ms (Flash) to ~500ms (v3) depending on configuration. ## Prerequisites - ElevenLabs SDK installed - Understanding of your latency requirements - Audio playback infrastructure (browser, mobile, server-side) ## Instructions ### Step 1: Model Selection for Latency The single biggest performance lever is model choice: | Model | Avg Latency | Quality | Languages | Use Case | |-------|-------------|---------|-----------|----------| | `eleven_flash_v2_5` | ~75ms | Good | 32 | Real-time chat, IVR, gaming | | `eleven_turbo_v2_5` | ~150ms | Good | 32 | Balanced speed/quality | | `eleven_multilingual_v2` | ~300ms | High | 29 | Narration, content creation | | `eleven_v3` | ~500ms | Highest | 70+ | Maximum expressiveness | ```typescript // Select model based on use case function selectModel(useCase: "realtime" | "balanced" | "quality" | "max_quality"): string { const models = { realtime: "eleven_flash_v2_5", balanced: "eleven_turbo_v2_5", quality: "eleven_multilingual_v2", max_quality: "eleven_v3", }; return models[useCase]; } ``` ### Step 2: Output Format Optimization Smaller formats = faster transfer: | Format | Size/Second | Quality | Best For | |--------|-------------|---------|----------| | `mp3_44100_128` | ~16 KB/s | High | Downloads, archival | |...
