If you own an Apple Mac or MacBook and want to create your own quality voice sound files using macOS Siri voices – read on.
This is the final product:
There is an existing, vast, downloadable collection of OpenTX sound files called “OpenTX Soundpack Joanne“, which might be more than enough for most of us. But if you have specific tracks to record, it is fast and easy to do it yourself.
For sound files to run on OpenTX 2.2.x or later, the following OpenTX specs apply – this is just FYI:
Don’t be put off by the technicality of those specs above. We will use a conversion website that will take care of all that.
First Step: Let’s have Siri produce the voice file
You obviously can replace the file name and the sentence you want Siri to say to whatever you like. Small hint: If you add a “,” (comma) in the text, it will create a slight delay between the words.
Second Step: Convert the .aiff file to .wav using the OpenTX specs
You’re done. Place that newly created sound file in the usual directory on your TX sd-card (E.g. SOUNDS/en/).
How to manage your sound files
To keep a record of the sound files created and to speed up the process, I use an Excel sheet that puts together the line to paste into Terminal based on my choice of file name and text I want Siri to speak. If interested, give me a shout. I am happy to share it. It looks like this:
If you want to create the Excel file yourself, the only tricky line is in column E, the formula is:
=B9&” “””&C9&””””&” “””&D9&””””
This formula combines the content of columns B, C and D in the proper format. Using this spreadsheet, all you need to do to produce a voice file is to copy the formula from column E into Terminal and press “enter”.
