Same voices, same quality, same price. It's already the cheapest model in Artificial Analysis' top ten, and the cheapest in model on Vapi's Humanness Index with a score of 97/100.</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Fah8ab8pyzztb4iqka5br.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Fah8ab8pyzztb4iqka5br.png" alt="Coval time-to-first-audio over 24 hours.

Simba 3.2 and Simba 3.0 are one per-character rate whichever endpoint you call, and the efficiency has not changed it.</p> <h3> Does the faster path change how Simba sounds? </h3> <p>No. The release changed where and how inference is served, not the weights or the voices. We've also snuck in watermarking to meet EU regs on generative content.</p> <h3> Simba 3.2 or Simba 3.0? </h3> <p>Simba 3.2 for English, because it has the most expressive delivery and now the lowest time-to-first-audio. Simba 3.0 if you need German, Spanish, French, Italian or Brazilian Portuguese, or self-serve zero-shot cloned voices. Our legacy Simba 1.6 supports more languages, and those languages will be finding their way into Simba 3.0 before mid-November hard switch-off of Simba 1.6. Simba 3.2 and Simba 3.0 both sit at around 100ms now, so pick on language and voice support.</p> <h3> How does Coval measure the 100ms? </h3> <p>Time-to-first-audio, from the request being sent to the first audible sample.</p> tts api speechify ai
