Arcana V3 Turbo

Architecture Overview:
• High-performance TTS optimized for real-time bilingual voice agents
• Native code-switching trained on bilingual speech patterns preserving prosody across language boundaries
• ~120ms time-to-first-audio on Together AI dedicated endpoints
• Efficient concurrency enabling higher GPU utilization for high-volume deployments
• WebSocket streaming support for real-time voice applications
• Co-located with LLM and STT workloads on unified infrastructure

Training Methodology:
• Trained on native bilingual speech patterns including pause placement and stress shifts at language boundaries
• Prosody optimization for English-Spanish code-switching within sentences
• Performance tuning for sub-200ms time-to-first-audio in production environments
• Emphasis and cadence modeling matching natural bilingual speaker behavior

Key Capabilities:
• English-Spanish Code-Switching: Native transitions with consistent prosody when callers switch languages mid-sentence
• Real-Time Performance: ~120ms time-to-first-audio leaves headroom for full voice pipeline processing
• Production Efficiency: Higher concurrency per GPU reduces infrastructure costs for high-volume deployments
• Natural Prosody: Pauses and emphasis match how bilingual speakers actually talk, not mechanical language switching
• Infrastructure Integration: Same API, authentication, and observability as LLM and STT endpoints
