Intent to Remove: SpeechRecognitionEvent's interpretation and emma attributes

[Philip Jägenstedt]

Specification

https://wicg.github.io/speech-api/ (does not have these attributes)

Summary

These attributes on the SpeechRecognitionEvent interface always return null, and were only added because they were at one point in the Web Speech API specification. They were removed from the specification in https://github.com/WICG/speech-api/pull/55.

I would like to deprecate the two attributes in M90 and remove them in M91. Risk of breakage is very low, but the deprecation message could help someone spot and remove unnecessary code.

The motivation for this is mainly to have the attributes out of the way if we unprefix SpeechRecognitionEvent, which is currently only accessible via the alias webkitSpeechRecognitionEvent.

Blink component

Blink>Speech

Risks

Very low. The usage for both is <0.00003%: https://www.chromestatus.com/metrics/feature/timeline/popularity/2481 https://www.chromestatus.com/metrics/feature/timeline/popularity/2482

Interoperability and Compatibility

Gecko: Speech Recognition not shipped, but these attributes are in Gecko's IDL. However, from what I can tell, they're always null as well. There are Gecko bugs filed for removing both interpretation and emma.

Edge: No signals solicited, this is a trivial removal.

WebKit: Speech Recognition not shipped, and not in WebKit's IDL.

Web developers: No signals solicited, usage is super low and there's no reason to use these attributes.

This intent message was generated by Chrome Platform Status. But had to be edited a lot by hand :)
