Known weaknesses
Each one links to the public issue, changelog or docs page it came from, where we have one.
- 01
Steep learning curve for non-C++ developers
Primary language is C++, which may be unfamiliar and complex for developers with different primary languages.
- 02
Limited documentation and examples
The official repository lacks comprehensive tutorials, making it difficult to understand advanced use cases without diving into the source code.
- 03
Performance issues on less powerful hardware
Voice AI functionalities can be resource-intensive and may lead to slow performance or crashes on embedded systems with limited processing power.
- 04
Small community support
The open-source project has a relatively small number of contributors, leading to slower issue resolution and feature development.
What it does well
Supports offline processing without internet connection
Works across multiple platforms including embedded systems and mobile devices
Offers a wide range of voice AI functionalities like speech-to-text, text-to-speech, speaker diarization
