AssemblyAI 正在区分其同步 API 和听写 API，两者均由其 Universal-3.5 Pro 模型提供支持。虽然两者都提供相似的转录速度和准确性，但听写 API 另外提供了一个清理过的口语文本版本，旨在用于不需要逐字准确性的应用程序。对于决定集成捆绑式听写解决方案还是将转录 API 与单独的语言模型结合使用的开发人员来说，这种区别至关重要。 AI

The Sync API and the Dictation API run the same model. The difference is whether you get the words as spoken, or also the words as meant. How to choose.
Should you buy a dictation API or wire speech-to-text to an LLM yourself? Here's the real cost of each path, in dollars, milliseconds, and engineering time.
Dictation APIs are judged on finished text, not word accuracy. Compare cleanup, latency, jargon handling, integration, and compliance before you buy in 2026.
A dictation API returns finished text; a speech-to-text API returns a transcript. Seven options compared on cleanup, latency, steering, and language coverage.
