Hi Roger,

as you suspected changing to SK1 removed all the problems with the speech appearing at the wrong times.

No, not at the same time. Once the voice prompts break, I was getting no more DMR voice at all. Repeater was active, I was seeing calls flash on the screen, and when I turned on my MD380 I could hear folks, but the GD77 was not making a peep until I cycled it.
I'm not sure what you mean by "voice prompts break"
Hi Roger,

I've been following this thread closely and the implementation in this test version is brilliant. I do see what KT4LH has reported. When I was playing with the vocal prompt feature and having the voice spell out alpha tags in the display the voice abruptly stopped vocalizing what was on the screen. At that point there was also no longer any audio when transmitting or receiving DMR transmissions. Powering the GD77 off and then back on again restored functionality. It seems like there might be some instability in the vocal prompt system in this experimental version.

Thanks Rob

The problem is probably being caused because the DMR part of the firmware is still running , and is probably resetting the audio buffers or the U2S DAC.

I will need to add some more code to prevent the DMR and also the FM signals killing the current audio prompt and getting everything in a mess

Glad Rob was able to describe it when I utterly failed ;) Thanks for all you do Roger!

Guys

I've uploaded a new Development version to github. You can download it from the same link as before.

Hopefully it should fix the problems with the voice prompts cutting out and locking things up, when a DMR signal is received or ends during the voice prompt playback.

Note. There may be still be some sequences of events which still cause a problem, so please let me know if you come across any..

Also.

Daniel noticed that the First In List beeps are not working when the voice prompts are enabled. This is an oversight by me, but Daniel has submitted a fix for this, in with a big load of other change to handle Long and Short presses of the Blue, Black and Orange buttons - which I now need to integrate and test.

I've now updated the firmware to include Daniel's enhancements and bug fixes

Roger,

I have not yet loaded the firmware with Daniel's changes, but the voice prompt fix released just before that seems to be working fine with no lockups after many uses of the voice prompt feature. It seems to be working very well. I'll load the latest release tomorrow and give that one a run.

Thanks again,

73, Rob W1AEX

Hi Rob

Thanks

The most noticeable differences with Daniel's update, is that to trigger the voice prompt, you must press and immediately release SK1 (Black) button.
Holding in SK1 just shows the channel information e.g. frequency and CTCSS settings etc.

Ken

It will get a lot better when I have time to re-make the AMBE audio files.
We can also do a British English version, as personally I don't like some of the current very American sounding audio.

I'm not sure why, but some of the letters of the alphabet seem to sound like they are said with a northern USA accent and some sound like they are from Texas or somewhere else on the southern border of the USA.

I'm intending to try to use audio generated by www.ttsmp3.com


But I've got some other code clean-ups to do first.
