AssemblyAI

AssemblyAI provides speech-to-text with built-in summarisation, sentiment analysis, and content moderation. It transcribes audio and video with additional NLP layers on top of the raw transcript.

I use AssemblyAI when a project needs more than just transcription - when you also want summaries, key topics, sentiment, or speaker identification from the audio. The combined pipeline saves building these layers separately.

For Barnsley businesses analysing customer calls or meetings, AssemblyAI provides transcription plus insights in one API. You get the transcript and the analysis - sentiment trends, key topics, action items - without building a separate NLP pipeline.
