Which one should you pick?
Pick IBM Watson Speech to Text if
You’re building around existing ibm cloud customers and call-centre platforms running watson assistant.. Watson STT was a pioneer that has been overtaken on raw accuracy. It still has a place in IBM enterprise accounts where the rest of the Watson stack is deployed, and the on-prem Cloud Pak option remains popular with banks.
Pick Otter.ai if
You’re building around meeting-heavy teams. Otter pivoted hard into meetings and away from straight transcription, which makes it great if you live in Zoom/Meet/Teams and want auto-summaries plus action items — and slightly awkward as a pure podcast transcription tool. The free plan caps you at 300 minutes and 30 minutes per file.
