Honest assessment
Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Google TTS API supports fewer languages and voices than competitors like Amazon Polly or IBM Watson Text-to-Speech.
Google imposes rate limits that may not suffice for large-scale text-to-speech needs, requiring additional cost to increase quotas.
The library is tightly coupled with Node.js and lacks official support or documentation for other runtime environments like Python or Java.
While the basic usage is covered, advanced features or troubleshooting guides are not as comprehensive.
