Today, in fitness clubs, training devices are lacking of accessibility: screens are too small, not enough light or contrast, keys are too small and not readable, flat keyboards,...
To overcome these issues, the idea is to command these devices (like a treadmill) using the voice, through an earplug or similar device.

The project aims to replace completely the console with voice enabled interactions.
The "Vocal Trainer" can give basic information like distance or speed, as a response to "get distance" or "get speed".
The user can command the treadmill with : "speed up", "speed down", "stop",...

The "Vocal Trainer" is hacking into the keyboard of the training device; it makes the appropriate contacts to replace physical key presses. The keyboard remains usable for any normal person.
By using this approach, it can be installed on any training device.
