Speechify Simba 3.2: Voice AI's Top Independent Benchmark

Speechify's Simba 3.2 has taken the number one spot on two independent voice AI benchmarks this week. It surpassed ElevenLabs and Cartesia in quality, speed, and price. For years, text-to-speech involved a trade-off: high quality meant high cost, and speed often meant compromise. This week, that rule changed. Simba 3.2 now leads the Artificial Analysis text-to-speech leaderboard, ranking above OpenAI and Google DeepMind. It also tops Voice Arena for real-time models at its price point. Both benchmarks are independent and use blind listener tests where native speakers vote for the most natural-sounding voice. Simba 3.2 is now the highest-rated real-time voice model available for production. It achieves number one quality ratings, offers sub-100ms latency for real-time responses, and is priced at $10 per one million characters, dropping to $6 on the Scale tier. This makes it the cheapest model in the Artificial Analysis top ten, significantly more affordable than competitors. This matters because it means top quality, speed, and affordability are now available in a single voice AI model.
