Fix speech to text accuracy problems with a smarter workflow

This guide explains that speech to text accuracy depends on audio input quality, speaker dynamics, and lexical and contextual issues, and that fixes should target the input, processing, or output stage of the pipeline. It recommends recording at 16 kHz or higher in lossless formats with microphones four to six inches from the speaker, using voice isolation, diarization or multichannel recording, and keyterm prompting, and measuring accuracy with word error rate. It also notes that ElevenAPI offers Scribe v2 with keyterm prompting, multichannel transcription, and speaker diarization.
