AssemblyAI
AssemblyAI is a Speech AI platform for developers and product teams. Its core capabilities include pre-recording and frequency transcription, real-time speech to text, speaker separation, keyword prompting, speech understanding, Guardrails, LLM Gateway and Speech-to-Speech interfaces. It is better for teams who are building meeting minutes, customer service quality inspections, voice agents, medical transcriptions, podcast analysis, or voice data products, rather than individual users who just want to manually transcribe a piece of audio occasionally. The official website provides documents, API Reference, Playground, status pages and price-by-product pages. Before use, it requires basic API integration capabilities, and pays attention to audio duration, model capabilities and data security requirements.
