Why does the the computer voice speak soy weird?

Answer 1

Computer 'voices' are electronically generated from a database of pre-recorded words. They do not instantly form sentences like humans do. Therefore, the person recording the words for the computer to speak doesn't necessarily speak the words as they would under normal speech. It's also done to save storage space on the device.

Take as an example, a sat-nav device speaking to a driver. The voice could say something like "At the next roundabout, take the third exit" - The word 'third' would likely sound 'funny' because the speaker records the sentence "At the next roundabout, take the exit". (with a short gap before the word 'exit'. The sat-nav stores that sentence, along with separately recorded words 'first', 'second', 'third' etc. The device then 'merges the relevant separate word into the incomplete sentence. Recording the directions that way saves memory - as the device only needs to store one copy of the main sentence - with enough gap to 'slot' in the relevant word - instead of storing the complete sentence for every exit from the roundabout.
