Anthropic
3.5

Ivona was acquired by Amazon in 2013 and discontinued as a standalone product; its technology was absorbed into Amazon Polly, making it obsolete and no longer actively maintained or developed.

OpenAI
4.8

Ivona was a notable TTS voice brand, but today it is largely legacy tech under Amazon Polly rather than a leading standalone AI voice product, so it feels dated and niche compared with current top-tier voice tools.

Gemini
1.5

Ivona was acquired by Amazon in 2013 and its technology integrated into services like Amazon Polly, meaning it no longer exists as an independent AI voice tool today.

Grok
2.5

Ivona was acquired by Amazon in 2013, its technology folded into Polly, and the standalone product has long been discontinued and superseded by modern AI TTS tools.
