AI Services in Speech Recognition & Synthesis

Tools leveraging AI technology to analyze and generate voice dataFeaturing 12 AI services in total.

サマリー

Sumarii

An AI transcription and meeting-minutes service designed for spoken Japanese. It handles microphone recording, audio and video files, media URLs, and meeting-bot invites to Zoom, Google Meet, and Microsoft Teams, taking you from a transcript with speaker labels and timestamps all the way to a templated AI summary on a single screen. Its distinguishing feature is that you can fix broken proper nouns on the spot — via a "words that need checking" list of low-confidence terms and natural-language edits through AI chat. Audio, transcripts, and minutes are stored in Japan and are never used to train AI (zero retention). Up to 3 hours a month is free with no credit card required, with every feature available.
