Improve captioning and translation quality

There are a number of things you can do to improve live caption quality.

Increasing the segment size of your HLS stream will allow CaptionHub to improve the caption quality. The recommended segment size is 10 seconds. The minimum is 5 seconds.

See how to increase the segment size in Brightcove.

Custom dictionaries bias the speech recognition towards certain words. In a live context, it is highly recommended that you configure a custom dictionary with speaker names, product names and other specific words that speech recognition might not pick up automatically.

Termbases are similar to custom dictionaries, but influence how words are translated. Use this to specify specific translations, or to avoid translating brand and product names.

Since CaptionHub Live using Amazon Translate, you can use the Amazon Translate specific features in your project.
