Isn't this already handled by the following add-on?:

Enhanced Phonetic Reading (EnhancedPhoneticReading)
add-on

The development channel has been tested with NVDA 2022 and it's rather certain that this will eventually become the production release.  The stable version is tested up through 2021.3

Chris,

The way I read the following in the documentation, "Read the character description instead of the current character. This feature must be enabled or disabled manually and will be deactivated when NVDA is closed," suggested to me that what you wanted is able to be turned on, but only on a "per NVDA session" basis.

Have you played with that option?

As do I.

Here's more from the documentation if you use the Add-On Help feature in Add-Ons Manager:
----

Usage

The add-on functionality will be enabled once you install it.
To enable or disable it, go to NVDA settings and select "Enhanced phonetic reading". In that category you can set the following parameters:

• Enable delayed descriptions for characters.
• Delay to announce character descriptions (in ms): the time the add-on waits to speak the description for the read character. You can't set it greater than 20000 ms.

Scripts

• toggle instant character descriptions: Assigned to "nvda + control + numpad2" or "nvda+ control + enter" for laptop keyboards. This script enables or disables the instant character descriptions feature.
• toggle delayed descriptions: no gestures assigned. This script lets you toggle the delayed descriptions status.

You can assign a command or gesture in speech category in the NVDA input gestures dialog.

----
 
It appears to me that you can get instant phonetic reading, and only phonetic reading, either by unchecking the checkbox for delayed descriptions or using the toggle keyboard command to turn it off.

I understand why many would not want to hear the letter first followed by its phonetic equivalent.  I'm actually surprised that this add-on is not set up with defaults that are the reverse of what they are, but it's configurable.

I used the dev version since I do have NVDA 2022 installed.

I'm curious about the JAWS feature.  Can you set the speed at which letters are announced and whether and how long ;pauses are between the announcement of individual letters?  I would think that if that weren't done, the letters might be announced so quickly you would lose track of them if you use a somewhat fast speech rate.

That's what I had in mind, the pause would be important, I think.

So, if I'm understanding you correctly, you want NVDA to detect that it has an unpronounceable alphanumeric string when it's doing a say all and, when such is encountered, say it phonetically?

It's not that something like this couldn't be done, but it does require quite a bit of overhead as each "word" would need to be analyzed as to whether it was an alphanumeric string in realtime, which is a non-trivial and resource intensive task (relatively speaking) since there is no way to predict where such might occur in a text.  Does the JAWS feature do this during a Say All?

And I did just play with the Enhanced Phonetic Reading add-on and if I use the NVDA + CTRL + NumPad 2 command I can toggle instant reading of each character phonetically and have it skip the regular announcement of the letter itself.  So, provided I'm going letter by letter, I get “Lima, 9, golf, 3, Sierra, 6” for L9G3S6.

Hi Group,

A simple way of describing this is indeed to have 'spell alpha-numeric expressions phonetically' active during screen reader 'say all' reading.  Here's an example. 

Say I have the following sentence in 'say all.' mode.
I just had a conversation with Robert smith WA2PDQ on the forty meter ham band. 
With 'spell alpha-numeric expression phonetically' turned on in JAWS, this sentence would be rendered in 'say all' mode as follows:
I just had a conversation with Robert smith Whiskey Alpha 2 Papa Delta Quebec on the forty meter ham band. 

This would be a nice feature if it could be implemented in NVDA.

Could it just be looking at words with caps inside the word other than at the start?

I'd still expect a lag though, unless it had already built up an index of such things in the document being read first which would delay the start of reading.
Goodness knows what it would make of nvda Python logs and code then! Grin
