Speech-to-Text

Round-Trip

TTS then ASR — tests full pipeline accuracy and latency.

Voice Cloning

Record a short speech sample, then use it as the voice for TTS. Both the audio and its transcript are required.

Step 1: Record Reference

Read one of these sentences naturally. 5-15 seconds works best.

Step 2: Verify Transcript

Auto-filled from your recording. Edit if needed.

Step 3: Generate with Cloned Voice

Concurrent TTS Performance Test

Fire parallel TTS requests to measure throughput, latency, and time-to-first-byte under load. Click any bar to play the audio.
