A few minor comments on Making Audio and Video Media Accessible

Hello Shawn,

Here are a few comments on last draft of making audio and video media 
accessible.

1. Audio description page: 
https://wai-media-guide.netlify.com/design-develop/media/description/
In "Tips for Recording Descriptions", typo: "Use a neutral voice that 
does nto convey emotions."


2. Captions page:

https://wai-media-guide.netlify.com/design-develop/media/captions/
In Caption Tools:
This sentence is not clear : "Most caption-editing tools provide can 
export a plain text transcript."
Two verbs?


3. In page transcripts: 
https://wai-media-guide.netlify.com/design-develop/media/transcripts/

In "does my media need a transcript"? There seems to be one word that 
should be deleted: "In a some cases, transcripts are not required to 
meet WCAG standards."


4. In page Sign languages: 
https://wai-media-guide.netlify.com/design-develop/media/sign-languages/

"Sign language is not required by most policies.
Sign language is in the WCAG standard at Level AAA. "
Shouldn't it be explained why it is not required. Often, deaf people are 
not satisfied that sign language is not available.
5. Accessible media players:

Typo in, player accessibility functionality: "More details on player 
accessibility functionalty are in a separate document:"


That's all!

Best and hearing from you in September!
