Solid for our team

We rolled this out across the team last quarter and real-time and batch transcription options. Cloud or on-premises deployment fits neatly into how we already work, and cloud or on-premises deployment removed a step we used to do by hand. but it has held up under daily use.

Does the job

Pretty happy overall. Cloud or on-premises deployment just works and strong support for enterprise and regulated industries. but no dealbreakers — I'd recommend it to a friend without hesitating.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on custom vocabulary and model training, and customizable language and acoustic models caught me off guard. still, I'd recommend giving it a real trial.

Use it every day

Honestly didn't expect to like it this much. Real-time streaming transcription is exactly what I needed, and real-time and batch transcription options. I do wish accuracy may trail leading competitors on some languages, but I reach for it almost every day now and it just clicks.

问答

Does the service support real‑time streaming as well as batch transcription?

It supports both real‑time streaming transcription for live applications and batch processing of uploaded audio files, with features like speaker diarization and word timestamps available in both modes.

Asked by Zeynep Aydin · Nov 27, 2025

What customization options exist to improve accuracy for industry‑specific terms?

The platform offers custom vocabulary and model training, letting you add industry‑specific acronyms, phrases, and accent variations to boost recognition accuracy for your domain.

Asked by Sven Bergqvist · Nov 14, 2025

Can the service be deployed on‑premises for data‑residency requirements?

Yes, Watson Speech to Text can run on‑premises via IBM Cloud Pak for Data, allowing organizations to keep audio data within their own infrastructure while still using the same transcription capabilities.

Asked by Xiomara Delgado · Nov 4, 2025

How is IBM Watson Speech to Text priced for high-volume usage?

Pricing is usage‑based and can become complex at scale; IBM offers a free tier with 500 minutes per month and tiered rates for additional minutes, with separate costs for custom model training and on‑premises deployment.
