Autohotkey and Text to Speech

Autohotkey and Text to Speech
« on: June 08, 2018, 12:28:18 PM »
Hello, I have posted some ideas in the past here and most of those posts were removed due to old age!  ::)

Autohotkey is a free and easy script package and once installed on your windows computer, all you have to do the double click or run the script.  Do a google search for autohotkey and you will find lots of information. There is even forums where many are happy to help you get your script working just as you need it. There is even a few programs that will record your mouse clicks and save them as macros in autohotkey script.  The possibility's to automate many items working with RadioDJ is possible.

Autohotkey even allows you to compile your script in to an executable  (.exe)  But, if you run your scripts as a .ahk ' you can mod the script at any time in a text editor, I like notepad++ because it has line numbers and you can easily debug your scripts.

Text to Speech and autohotkey is something I have been using for many years and even though a plugin was made for RDJ, I still prefer to use the script based method because I can quickly and easily make changes as needed.

Windows OS has built-in text to speech engine located in windows control panel/ speech recognition/ text to speech/  You can find with a little searching many voices that can be easily installed on your pc.

The text to speech plugin for radiodj makes .wav files to mix properly with rdj sound output and is very good, however, for me, the voice would come in too quick and some late night announcers allow the music to cross fade slowly and then start announcing. This delay is easy to control with a autohotkey script.  Speech scripts use windows audio out and so a virtual mixer or external mixer may be required to get the proper balance from voice over music.

I will post the following script I am currently using and if you read line by line, you can see the possibilities, over the years I have simplified what I like, but I have many versions, where you can do trivial data base and comment on bands, have multiple calls for different voices, like a female voice to give time and weather and a male voice to announce the artist and title. You can have many voices as long as they do not overlap, the sapi voice engine is not good at multi-tasking.

Here is the script and to use it, you would copy and paste into a text editor and save as announcer1.ahk or something like that. I have over 24 of these scripts in a directory and use RDJ events to call up the script every hour to announce the rotation, time and dj etc...

Read the ; comments in the script to understand whats happening  Note:not placing in script quotes to make this easier to read

;Begin script
; Voice announce Zera @ 1am playing ambient until 9am
; ahk script by Compdoggie
#SingleInstance force
;2hours is -7072000 time is in ticks or basically in seconds  my scripts time out and kill themselves before RDJ next event when a new ;script is called up

Newstringfinal := RegExReplace(NewString, "REM", "`R E M ")
If Newstringfinal contains PSA,NPR,UNK ; if the string contains any of these it will not announce good for PSA, songs with talking at ;beginning

    Random, rand, 1, 15 ; set the value to the number of variations in the announcement saybefore or after 15 random sayings

;end script

Currently running this script with radiodjv2   I run a 1tb drive with c:\ as 200 gig OS and a D:\ as the Radio:\ drive for mariadb, shoutcast, a-----t encoder, radiodjv2 dir running 

Hope this sheds some light on text to speech and the awesome tool called autokhotkey!

Thanks to Marius for such an enjoyable addition to my life!  :ok: RadioDJ!
