OP here. The more you use, the cheaper it gets. But if you're not using much, there isn't any cost-saving benefits.

Once you scale to ~60M characters per month, it's 50% cheaper. In other words, if you're at a stage where you spend $1,000/mo on text-to-speech, you'd spend $500/mo instead.

Do you support SSML and other languages besides English? The demo site suggests not, and I couldn’t explore further without signing up.

This service might be cheaper than Google at scale, but if I needed 60M chars a month I’d probably care about those features.
