Acapela Tts Demo Verified — [top]
- Latency: Time from hitting "Speak" to audio output. Verified demos typically achieve sub-200ms for short sentences via streaming APIs, but the demo shows you the raw speed.
- Consonant Clarity: Listen for plosives (P, T, K) at high volumes. Distortion is a sign of poor encoding.
- Unit Selection vs. Neural: Acapela now uses HMM (Hidden Markov Model) and Neural Hybrid engines. The verified demo will label which engine is active.
- SSML Support: Verify that
<break time="1s"/> actually inserts a one-second pause.
- Fallback Handling: What happens if you type an emoji or ASCII art? (e.g., "Hello <3"). A robust engine handles it gracefully.
