## Choose when

### Choose espeak-ng if…

- License: espeak-ng is GPL-3.0, Fun-ASR is Apache-2.0.
- Tags unique to espeak-ng: android, espeak, espeak-ng, speech-synthesis.
- When multilingual support across over a hundred languages is required.

### Choose Fun-ASR if…

- License: Fun-ASR is Apache-2.0, espeak-ng is GPL-3.0.
- Pricing: Open source under Apache License 2.0 allows free use with attribution and adherence to the license terms..
- Requirements: Installation requires Python packages `funasr` version >=1.3.3, and `vllm` version >=0.12.0..
- Tags unique to Fun-ASR: asr, audio-language-model, multilingual-asr, real-time-asr.
- Also covers LLM Frameworks.
- When you need support for 31 different languages including handling of various dialects and accents.

## When NOT to use espeak-ng

- Avoid if proprietary software development prohibits use of GPL-3.0 licensed tools.
- Not ideal if fine-grain control and quality over diverse accents are more important than extensive language coverage.

## When NOT to use Fun-ASR

- Avoid if your project requires a specific programming language other than C as Fun-ASR is primarily developed in C.
- If you do not require on-device processing, as this tool is designed for on-device inference which may limit scalability for cloud-based applications.
