# EmotiVoice vs TensorFlowTTS

*GraphCanon updated Sep 20, 2026*

## Verdict

Pick EmotiVoice if emotiVoice is an emotion-driven text-to-speech engine that emphasizes voice diversity and prompt control, allowing users to generate speech with varied emotions and speaking styles; pick TensorFlowTTS if tensorFlowTTS is notable for its real-time speech synthesis capabilities with support for multiple languages and advanced models like Tacotron2, FastSpeech2, MelGAN.

[EmotiVoice](https://github.com/netease-youdao/EmotiVoice) reports 8.5k GitHub stars, 756 forks, and 137 open issues, last pushed Sep 3, 2026. [TensorFlowTTS](https://tensorspeech.github.io/TensorFlowTTS/) has 4.0k stars, 797 forks, and 2 open issues, last pushed Jul 5, 2024. Figures are from public GitHub metadata via [EmotiVoice's repository](https://github.com/netease-youdao/EmotiVoice) and [TensorFlowTTS's repository](https://github.com/TensorSpeech/TensorFlowTTS).

## Choose when

### Choose EmotiVoice if…

- Tags unique to EmotiVoice: ai, deep-learning, emotion, multispeaker.
- When you need a TTS solution capable of handling multiple speaker voices in a single project
- More GitHub stars (8.5k vs 4.0k) - visibility, not fit.

### Choose TensorFlowTTS if…

- Tags unique to TensorFlowTTS: chinese-tts, fastspeech, fastspeech2, german-tts.
- When you need state-of-the-art real-time text-to-speech functionality across several languages including English, French, Korean, Chinese, German,
- Leaner open-issue backlog (2).

## When NOT to use EmotiVoice

- For setups without access to an NVidia GPU, as EmotiVoice requires one for running its Docker image
- When deploying applications that have strict latency requirements and cannot accommodate the startup time of a Docker container or the processing demands of GPU computations

## When NOT to use TensorFlowTTS

- When you require a text-to-speech solution that works on operating systems other than Ubuntu 18.04 as it has been tested only on this specific environment
- If your project cannot meet the hardware requirements such as needing CUDA 10.1 and CuDNN 7.6.5, or if you want to avoid dependency on TensorFlow-specific packages like TensorFlow Addons
