SpeechifyAI's Simba 3.2 is now the fastest model on the @voicearena_ai US English 🇺🇸 latency board: 123.0 ms to first audio at the median, climbing from #9 at 392.5 ms in its earlier series. SpeechifyAI shipped serving-side updates, our latest measurement series picked them up, and the ranking moved. That is exactly what measuring in public is for. At 123.0 ms it sits 45.5 ms ahead of Inworld TTS 2 at 168.5, more than three times faster than its own earlier number, and with a quality rank range of 6 to 8 on the same 20-model board it joins the quality-versus-speed frontier. Rank the board by TTFA yourself → voicearena.com/tts-leaderboa… Congratulations to @SpeechifyAI 👏

Two independent benchmarks in two days, both put Simba 3.2 at blazing fast speeds, while being top for benchmark quality and 10x more affordable than labs. Coval measured Simba 3.2 at 106 ms to first audio, Voice Arena at 123 ms, the fastest on their US English board. Same voices, same price, no code change. Chart: Voice Arena

Filtered to real-time models, Simba 3.2 from @SpeechifyAI leads at 1053, a clear margin ahead of the rest of the field. The contest is behind it: Grok TTS (1030), Maya-2-Global (1026) and Sonic-3.5 (1026) sit within four points, with Maya and Cartesia level on the same score. At that spacing, the ordering is a statistical tie rather than a ranking.

Ran your public surface through our benchmark this week — Accessibility 100 and Reliability 100. For a voice product, nailing accessibility isn't a nice-to-have, it's the whole point. Respect.

Speechify's infrastructure was a bottleneck. Now they serve dynamic pages to 60 million users on Vercel using Next.js, Cache Components, and Instant Rollbacks. "Without Vercel, we couldn't compete at the speed this market demands." vercel.com/blog/how-speechif…

I am so confident in our latest model I put it AND our competitors on the hero of our homepage for people to blind test lol - no tricks just audio we just debuted 2nd on @voicearena_ai at $6/M. the model we tied with is $50. go pick a winner speechify.ai

When you tie on quality, but you're real-time and 7 times cheaper than the next-best streaming model... @SpeechifyAI just proved why we're the best TTS API provider on the planet right now On @voicearena_ai - we took joint 2nd overall and cheaper than our 2nd-place rival. 1st place isn't even real-time. Our labs team has taken our long-running success in consumer text-to-speech and is now challenging developers and competitors alike. Is $100/1M characters really worth it? All the leaderboards say no, the latency says no, the uptime says no – what does that other $94/1M characters buy you these days? speechify.ai/blog/simba-3-2-…
