Compared a few options

Evaluated this against two competitors. Where it wins: downloadable audio output and customizable voice options. On balance the feature set — especially downloadable audio output — justifies the 5 stars for our use case.

Use it every day

Honestly didn't expect to like it this much. Multiple natural voice options is exactly what I needed, and customizable voice options. I do wish may lack advanced SSML controls, but I reach for it almost every day now and it just clicks.

Solid for our team

We rolled this out across the team last quarter and supports six languages. Multilingual text-to-speech in 6 languages fits neatly into how we already work, and downloadable audio output removed a step we used to do by hand. but it has held up under daily use.

Years in this space

I've evaluated a lot of these over the years. What stands out here is customizable speech settings — handled better than most — and fast, near-instant generation. Quality varies by language is my one real gripe. Worth the time if this is your use case.
