Tacotron 2

End-to-end text-to-speech synthesis using sequence-to-sequence models.

score4.9/10

Tacotron 2 is an end-to-end text-to-speech synthesis model that converts written text directly into natural-sounding speech using sequence-to-sequence neural networks. It combines a sequence-to-sequence model with a WaveNet vocoder to generate high-quality, intelligible speech with natural prosody.

Anthropic

4.2

Tacotron 2 is a landmark 2017 research model now in maintenance mode; while historically influential, it's been superseded by faster, higher-quality systems like Glow-TTS, FastPitch, and commercial APIs, making it primarily academic rather than production-viable today.

OpenAI

7.0

Tacotron 2 was a landmark TTS model and remains educationally important, but in today’s market it is largely a dated research baseline rather than a top production voice tool, with modern neural TTS systems generally outperforming it in quality, speed, and usability.

Gemini

4.5

While historically foundational for TTS research, Tacotron 2 is largely superseded by more advanced and efficient models in 2026, rendering it dated and limited for competitive current market applications.

Grok

3.8

Tacotron 2 (2017) is a foundational but long-superseded research model, now outdated in a 2026 market dominated by far more advanced commercial and open-source TTS systems.
