GPS Voice

The voice of a GPS app used to be recor­ded in a stu­dio — until TTS was developed

A GPS voice tells you to “turn left” or when to take an exit. In the ear­ly days of GPS Navi­ga­ti­on apps all the­se stan­dard announce­ments used to be pre­re­cor­ded audio snip­pets from pro­fes­sio­nal voice artists. The GPS soft­ware would con­ca­te­na­te the parts to form ins­truc­tions like “In” — PAUSE — “100” — PAUSE — “meters” — PAUSE — “turn left!”.

Navi­ga­ti­on com­pa­nies like info­wa­re would send voice artists to stu­di­os to record indi­vi­du­al phra­ses like “100”, “150”, “500” etc. You would also need “turn left!”, “turn right!” and “keep left!” and so on and so forth. That was quite expen­si­ve as it was requi­red for mul­ti­ple lan­guages too!

New Fea­tures Made Pos­si­ble By Text To Speech (TTS)

And of cour­se you could­n’t tell the dri­ver to “turn right into Main Street”. Becau­se then you would need to all the mil­li­ons of street names. Also, you can­not add your own spo­ken ins­truc­tions to a rou­te. But this is a fea­ture that would be very hel­pful for many navi­ga­ti­on applications. 

In our Fol­low­Me navi­ga­ti­on you can insert your own per­so­nal ins­truc­tions in a rou­te that your collegue will dri­ve. This is being used in waste manage­ment for instance. Here, you can tell the dri­ver to “Mind the low han­ging branch!” which every roo­kie dri­ver has slam­med into at least once. In win­ter the voice out­put is used to give addi­tio­nal dri­ving ins­truc­tions at loca­ti­ons that need extra attention.

In the first video we show how Text-To-Speech soft­ware is used to insert cus­tom voice ins­truc­tions to impro­ve rou­te gui­dance and to master dif­fi­cult dri­ving tasks.

In the second video you can see how the voice navi­ga­ti­on system is used at Leip­zig Air­port for win­ter road main­ten­an­ce. With Map­Trip Fol­low­Me, the com­pa­ny GPSo­ver­IP has built a solu­ti­on that tells the dri­vers exact­ly whe­re to sprink­le with salt and whe­re not.
