Creating OpenTX Soundpacks
OpenTX is provided with the possibility to use sound packs.
These are audio (wav) files, and you can play these from OpenTX.
Like many have heard on the field 🙂
To put together a sound pack quickly and easily, there is a program called “TTS Automate”
This program converts a piece of text to audio and saves it in a specified folder and name.
The spoken language can also be selected.
It looks like this.
- Line number
- Folder / Each line contains the path where audio file is stored.
I always maintain the structure of the SD card of OpenTX directly
- Filename / the name of the audio file (note! From OpenTX v2.1.x a maximum of 6 characters are allowed, if larger they are ignored by OpenTX)
- Phrase to Speak / Here the text that the audio file should receive. Occasionally you may have to play phonetically to get things properly spoken.
See inter alia lines 201 and 204 🙂
- Play / Plays the file, and the file is created directly in the specified path
To the right of the screen:
- Open Phrase file / here you can select the .PSV file
- Select Output Directory / Where eventually the output including the specified path structure should be placed.
- Create new Phrase File / Create a new project with this
- TTS Provider / Select the Text To Speech Provider here. (To date, only Amazon Polly works correctly)
- Voice / Select the voice here (I myself use Dutch Ruben, and I use Matthew for English)
Settings of TTS Automate so that they work well with OpenTX.
Most important here is the Voice Options
- Encode MP3 to WAV (checked)
- Sample Rate: 32000Hz
- Bits per sample: 16
