Steps to reproduce:

  1. Create html test page with the following content: <!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Title</title></head><body><span>b4Z9e24-Rd8</span></body></html>
  2. Open test page in Chrome
  3. Navigate with NVDA to the text ("b4Z9e24-Rd8")

Actual behavior:

NVDA reads text as "B four Z nine times ten to the power of twenty four R D eight"

Expected behavior:

NVDA should read the text as "B four Z nine E twenty four dash R D eight"

Hi, looks like this may have to do with speech synthesis engines. Can you try using a different speech synthesizer (Control+NVDA+S, select a different engine) and try reproducing this? If NVDA says something else when encountering the example text, then it’s something beyond NVDA itself and may need to be discussed with TTS manufacturers and/or resolved through speech dictionaries. Thanks.

Hi @josephsl , looks like changing the engine helped. However dash is still not announced.

Is this the engine issue?

josephsl commented 3 years ago

Hi, you can resolve it by going to NVDA menu/Preferences/Punctuation/symbol pronunciation, locate the symbol you want, then set the level to whatever your current punctuation level is set to. Thanks.

That didn't help. Still can't get it work with "dash"

The issue with exponent is resolved by changing the engine to Microsoft Speech API version 5 and the voice to Microsoft Zira Desktop. Same synthesizer announces exponential value when Microsoft David Desktop voice is used.

Is this still the engine issue?

Hi, in this case, the next possible solution to try will be defining a speech dictionary entry that will let NVDA announce UUID correctly (it is preferable to use regular expression for this). Thanks.

Hello Probably a duplicate of #8959. Or at least, two different problems for a similar cause.

ernistkg commented 3 years ago

Yes, it is similar. But the context is different - Web/Excel

ehollig commented 1 year ago

Although one of these issues is in Excel, and the other is on the web, both require updates from Microsoft in SAPI5 or Onecore. @Qchristensen outlines this in https://github.com/nvaccess/nvda/issues/8959#issuecomment-662884978
