To Enable

View -> Options -> Channel Announcement Options Check the "Read/Write Voice Files" box. Save, close and re-open the CPS after this. Radio Configuration -> Radio Wide -> General Check the "Channel Announcement" box. Leave the priority at low.

Create Your Announcement Files

They must be 8 kHz, 16-bit mono-formatted WAV files.

Here are some compatible WAV files for radios with voice Channel Annoucements:

Female Voice * Brown County EMS * Brown County Fire Dispatch * Brown County Sheriff Dispatch * Green Bay EMS * Green Bay Fire Dispatch * Green Bay Police Tac B * Ashwaubenon Police Dispatch * Scan Green Bay * Scan All Computer Voice AshDP Main DTF Tac 4 BC Interop 8 BC Tac 10 BC Train 13 GBPD Main Oneida Main AshDP TTY BC EMS BC Interop 9 BC Tac 11 BC Train 14 GBPD SWAT Main Scan All BC Admin BC Fire Main BC Law Emgcy BC Tac 6 DP Admin GBPD Tac B Scan Green Bay DTF Tac 1 BC Interop 2 BC Rural Admin BC Tac 7 GBFD EMS #2 GBPD Tac E DTF Tac 2 BC Interop 3 BC Sheriff Main BC Tac 8 GBFD EMS #1 GBPD Tac F DTF Tac 3 BC Interop 4 BC Sheriff Tac 4 BC Tac 9 GBFD Main GBPD TTY

To generate a text-to-speech WAV file (computer voice) under Linux:

$ espeak -w GBPD-Main.wav "Green Bay Police - Main"

Then to convert that WAV file to a 8 kHz, 16-bit mono-formatted WAV file:

$ sox GBPD-Main.wav -b 16 8bit-GBPD-Main.wav channels 1 rate 8k

The new file, 8bit-GBPD-Main.wav is then ready to be converted and loaded in CPS.

Those 8-bit WAV files MUST also be converted to a proprietary MVF format.

To convert WAV to MVF:

Tools -> Voice Files -> Voice Files Compression

Copy the 8-bit WAV files to:

C:\Program Files\Motorola\ASTRO 25 Products\ASTRO 25 Portable CPS\Voice

Then import the .MVF files into the CPS:

File -> Import -> Voice File

The new MVF files will also be in the same directory.

Unfortunately, this all must be done one file at a time.

Assign Voice Files to Channels

From there you can assign the MVF files to channels under the "Zone Channel Assignments."
