# dc_tts vs TTS

*GraphCanon updated Jul 30, 2026*

## Verdict

Pick dc_tts if dc_tts is a text-to-speech model based on TensorFlow and requires specific version dependencies; pick TTS if tTS is known for its deep learning capabilities in text-to-speech synthesis and supports Python versions up to 3.8.

[dc_tts](https://github.com/Kyubyong/dc_tts) reports 1.2k GitHub stars, 360 forks, and 68 open issues, last pushed Apr 14, 2023. [TTS](https://github.com/mozilla/TTS) has 10k stars, 1.3k forks, and 37 open issues, last pushed Nov 9, 2023. Figures are from public GitHub metadata via [dc_tts's repository](https://github.com/Kyubyong/dc_tts) and [TTS's repository](https://github.com/mozilla/TTS).

- **Requirements:** Depends on TensorFlow >=1.3 and has compatibility issues with updated APIs for `tf.contrib.layers.layer_norm`.; Requires Python packages like NumPy, librosa, tqdm, matplotlib, and scipy.
- **Adopt for:** dc_tts is a text-to-speech model based on TensorFlow and requires specific version dependencies.

## Decision facts: TTS

- **Adopt for:** TTS is known for its deep learning capabilities in text-to-speech synthesis and supports Python versions up to 3.8.

## Choose when

### Choose dc_tts if…

- dc_tts is primarily Python; TTS is Jupyter Notebook.
- License: dc_tts is Apache-2.0, TTS is MPL-2.0.
- Requirements: Depends on TensorFlow >=1.3 and has compatibility issues with updated APIs for `tf.contrib.layers.layer_norm`.; Requires Python packages like NumPy, librosa, tqdm, matplotlib, and scipy..
- Tags unique to dc_tts: speech, speech-to-text, tensorflow, tts.
- dc_tts is a text-to-speech model based on TensorFlow and requires specific version dependencies.

### Choose TTS if…

- TTS is primarily Jupyter Notebook; dc_tts is Python.
- License: TTS is MPL-2.0, dc_tts is Apache-2.0.
- Tags unique to TTS: dataset-analysis, deep-learning, gantts, glow-tts.
- Use TTS when you require advanced deep learning models such as Tacotron, Tacotron2, MelGAN, and Multiband-MelGAN for high-quality voice synthesis tasks.

## When NOT to use dc_tts

- Last GitHub push was 1229 days ago (dormant maintenance, Apr 14, 2023). Validate activity before betting a new project on dc_tts.

## When NOT to use TTS

- Avoid TTS if you require support for Python versions above 3.8 as it does not support later releases.
- Do not use TTS if the only requirement is to run simple, unmodified speech synthesis tasks without training or custom development; other tools may offer easier setup.
