AI Transcription and Speaker Detection
Castmagic transcribes your recordings using AI speech recognition that supports 60+ languages, identifies individual speakers, removes filler words, and adds timestamps. For most English-language podcasts recorded in decent audio conditions, accuracy is in the 90-95% range — good enough that the generated content downstream is usable with light editing. Speaker labels make it easy to attribute quotes in show notes and blog posts. The limitations show up in edge cases: heavy accents, overlapping speakers, background noise, and domain-specific terminology (medical, legal, crypto) all reduce accuracy. If your podcast frequently features guests calling in on poor connections or uses niche vocabulary, plan to review and correct the transcript before trusting the AI-generated content that builds on it. Castmagic does not currently let you add custom vocabulary or train it on your specific terminology.
