Honest assessment
Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Say.js relies on external plugins for TTS engines, and the ecosystem of available plugins is small and not actively maintained.
The official documentation lacks comprehensive examples and detailed explanations for advanced use cases, making it difficult to fully leverage the library's capabilities.
Say.js can become slow when generating a large number of audio files simultaneously due to its synchronous nature and lack of built-in concurrency support.
Switching between different TTS engines requires significant code changes, as each plugin has a unique API and configuration options.
