Speech to text on Mac: built-in dictation vs. the alternatives
Blog post from AssemblyAI
macOS includes free, mostly on-device dictation that can be enabled in Keyboard settings and used through a microphone key, shortcut, or menu command in most text fields, with users speaking punctuation and formatting commands aloud. Its principal strengths are privacy, no subscription, and offline-capable local processing, but it provides largely verbatim transcripts, lacks custom vocabulary, can struggle more with accents or noisy environments than hosted models, and cannot switch languages within a sentence. The comparison frames alternatives around the tradeoff between privacy and polished output: local tools such as Handy and FluidVoice use on-device models and retain audio locally, while cloud or hybrid tools such as Blurt, Superwhisper, and MacWhisper may offer stronger recognition, cleanup, formatting, custom terms, and language features but can require payment or send audio to servers. It also notes that developers can integrate speech recognition through an API rather than using a standalone app, and concludes that the appropriate choice depends chiefly on whether a user prioritizes local processing, improved transcription quality, automated editing, or product integration.
