Selecting a voice
How do computer voices work?
Your TomTom GO makes use of text-to-speech technology to generate com-
puter voices. A text-to-speech program converts written text, for example an 
instruction like “Turn right”, into the sound of a human voice. 
The text-to-speech program looks at the whole sentence to make sure that the 
sound you hear is as close to the real thing as possible. The program is also 
able to recognise and quite accurately pronounce foreign place and street 
names. For example, the English voice can read French street names.
Note: If you select a Human voice, this will only be able to announce com-
mands, but not street names. If you would like street names to be announced, 
you will need to select a computer voice.
Internal and external speakers
Your TomTom GO contains a high quality speaker. This is used to play all the 
sounds on your GO unless you select to play some sounds through external 
speakers.
The following types of sound can be played through the speakers as listed 
below:
• Spoken instructions and warnings:
• The speaker inside your GO
• An external Bluetooth® Hi-Fi headset or speakers
• Using an audio cable.
• Phone calls
• The speaker inside your GO
Note: If you wish to use an audio cable, an Active Dock with an audio connec-
tor is available as an accessory. Your car stereo needs a line-in connector. Not 
all car stereos have line-in connectors. Check the instructions for you car 
stereo for more information.

preferences
To change the voice being used by your TomTom GO, tap Voices in the 
Preferences menu, then tap Change voice. Select a voice from the list.
Your TomTom GO has two different kinds of voices:
• Computer voices
These are generated by your GO. They provide spoken instructions 
while you are driving and can pronounce street names and announce 
messages, traffic reports, weather reports, tips and tutorials.
•Human  voices
These are recorded by an actor.
Note: Human voices only provide spoken instructions.
