RiseFinder summary

AssemblyAI offers an API that turns spoken dictation into text for applications. The Dictation API accepts an utterance and produces text for a user’s writing. It can resolve self-corrections and remove filler from the output. Developers can provide context about their application and domain to guide transcription. The API also provides a verbatim transcript alongside the edited text. Audio can be sent in chunks as it is captured. AssemblyAI has released an open-source Mac dictation app built on the API.
