TOOLKIT OVERVIEW

The Graupner radio has hundreds of voice files that make up the many different voice announcements on the radio. They are used for system notifications, telemetry announcements, and more.

The radio voice files are stored in different folders on the internal SD card and are accessed by placing the radio in mass storage mode.

Each language has its voice files stored in its own folder, where each folder contains voice files related to the type of function it represents.

For example, the "06_Telem" folder contains the telemetry announcements, and the "09_Units" folder contains all the unit's voices to describe numerical values.

Each voice file has a unique name prefixed with a number for identification by the radio and which is also used during updates.

We do not recommend making changes to these files, but if you do, make sure to test for the proper working of the changed voice files especially when they have already been used in a working model

CREATING VOICE FILES

There are two easy ways to create voice files. The first way is manually by using the HOTT-TTS utility.

This utility is part of the firmware upgrade studio software and is recommended when you only need to create a few voice files.

If you want to change multiple voice files, for example, from male to female, or to a different language, you can use a free program called TTS Automate that uses phrase files which can be downloaded from our website. Those files can also be found on your SD card voice folders.

USING HOTT-TTS

Ensure the firmware upgrade studio is installed on your computer before continuing and then follow the six steps below.

Connect the USB cable from the radio to your computer and set your mz-16 or mz-32 in storage mode.

Load the firmware upgrade studio, scroll down and click on the "Link" icon and expand it. Look for the "HOT TTS" entry and click to open it.

After loading the "HOTT TTS" program, you will need to select a TTS provider. The default is the one available with a windows ten installation. Make sure that the audio output quality is a 24KHz.

You can use other TTS providers such as Amazon Polly or VoiceRSS. You will need to enter an API key which can be obtained mostly for free on the provider's website.

Type a word or phrase and press the test button to hear the voice. You can experiment with different volume and speed settings for further fine-tuning.

When satisfied with the results, click save button to save the file to your radio.

We recommend saving the voice file in the 10_User folder.

USING TTS AUTOMATE

If you want to make changes to all the voice files at once and generate new ones, you can do this with a freely downloadable program called TTS Automate.

TTS Automate can load a so-called phrase file which contains all of the voices that are installed on your radio from where you can add new voices or change each voice and have the program automatically generate the files for you.

This allows you to generate voices in different languages, other dialects or change the voices from female to male.

You can download the program at TTSAUTOMATE.COM.

Follow the six steps below to generate voice files.

After installing TTS Automate, load the program and go to the settings menu.

Verify your settings as shown above.

Download a phrase file for your language or radio SD card and copy it to a working folder of your choice. We recommend using the same output directory for the generated files.

Next you will need to open the phrase file which was copied earlier to your output directory.

After loading the phrase file, the main screen shows all the voices stored in the phrase file. Each voice line has a folder name, filename, and phrase to speak entry.

For example, the first entry will be stored in the 02_Func folder with the file name 001_Engine_mst and has a spoken word of Engine master.

At this point, you can start making changes to the phrase file. You can add, delete or modify the phrase to speak and test it by clicking on the preview button. You can experiment with different TTS providers to find what works best for you.

When finished, click on the Go! button to start generating the new voice files to your default output directory.

After generating the new voice files, there will be an mp3 folder used to create the wav files. The generated wav files are stored in the wav folder and are compatible with the file format needed on the mz-16 and mz-32 radio.

You can further enhance those files with programs like Audacity where you can increase the speed, tempo, or volume of the voices and more.

NOTE!

When making changes to the voice files, we recommend that the prefix number of each voice file is not changed as it may be needed by the radio to generate announcements.

You can change the existing phrase but not the number associated with it. If you make changes, make sure to test those changes carefully. If you want to add your custom voices, have them stored in the 10_User folder.

You can download a separate phrase file from our website for such a purpose.

INSTALLING

To install the voice files, you will need to manually copy the contents of the WAV folder to your radio SD Card. You need to set the radio to mass storage mode to do so.

At this point, you will have a few options available.

You can copy the files to your existing language folder, for example, EN for English, and overwrite the existing voice files. Please note that the files may be overwritten if you do a software update that includes voice resources.
You can use another language voice folder and copy the voice files to that folder by overwriting the existing voice files. You will have to activate the new files in the system set menu by selecting the language you used to enable the new files. A radio restart will be required. Note that only the voice files will change and not the radio language. This option allows you to use and switch between multiple voice files.
As of software release 2.024 you will find a DV folder in the main voice folder. This folder is a dedicated user voice folder where you store your voice files, which will not be affected by future software resource file updates. You can enable it in the system set menu on your radio by selecting User Voice, and a radio restart will be required. Note that only the voice files will change and not the radio language.

You will have to either manually copy the 01_Beep folder from another directory or use the firmware upgrade studio to create the DV folder and copy the 01_Beep folder to your radio.
