Hello. I was wondering if will it be possible to do the following :

1) When a specific voltage is sense and is displayed on the textbox, is there any codes to allow the audio announcement of the voltage ?

(a) As voltage levels will usually be in decimal, like for example, (1.23 V) ,
it may be difficult to allow the audio announcement of exact voltages
like 1.23V?

(b) Do i have to do a pre-recording of the audios ? So that when a specific voltage is sense and displayed on the voltage level textbox, the program will call out the audio and play it out ?

If any of the above explanation is unclear, do inform me. =)
Anyways, Thanks in advance to everyone for your time in reading / responding / guidance on this.
