What SpeechEvalPro API is
SpeechEvalPro API is a voice evaluation API for Chinese and English pronunciation. It is built on the provider's own education AI voice models and combines speech evaluation with speech recognition to score multi-dimensional aspects such as completeness, accuracy, and fluency. It accepts both voice and text input and supports different evaluation scenarios, including homework and exams, over HTTP and WebSocket protocols. Pricing includes free trials plus professional and enterprise versions, so teams can test before scaling. The target users are companies and developers building intelligent learning products that need machine scoring of spoken language, which means integration work is part of the deal.
What you can do with it
- Score pronunciation across several dimensions
- Evaluate both Chinese and English speech

Who it is for
- Teams building language learning products

What to watch out for
It is a paid API with a free trial, so full use requires a professional or enterprise plan. Integration takes development work, since you call the API over HTTP or WebSocket and build the feedback into your own product. Scoring is model-based, so borderline speech can get inconsistent results, and you should confirm current pricing and terms, including any access limits, before you rely on it in production. For team use, agree on naming and editing conventions in advance to avoid version conflicts or duplicated work. Name and archive exported files consistently so you can find and reuse them, and keep a backup copy of key data.
