Speechify AI - Simba Voice Agents

What is Simba 3.2 and why is it ranked #1?

Simba 3.2 is SpeechifyAI's flagship text-to-speech model ranked #1 on the Artificial Analysis TTS leaderboard. It delivers sub-100ms latency while maintaining the highest quality audio and remaining the most affordable option in its class.

How does zero-shot voice cloning work?

Simba can clone any voice from as little as 10 seconds of audio reference. It captures speaker identity including timbre, cadence, and micro-expressions to generate natural-sounding speech in that voice.

What languages does Simba support?

Simba supports native-quality synthesis across 30+ locales including en-US, es-MX, fr-FR, de-DE, ja-JP, pt-BR, and more. Each language uses voices recorded in that locale for natural pronunciation and prosody.

Can I control emotions in generated speech?

Yes, Simba models emotion at the prosody level, allowing you to generate the same text with different emotional expressions (neutral, happy, sad, excited, calm) through subtle rhythmic and tonal patterns.

How do I integrate Simba into my application?

SpeechifyAI provides a simple REST API for streaming, voice cloning, and emotion control. You can access all models with a single API endpoint using your API key.
