android navigation - voice options

[Paul172sport]

I've got the standard Google navigation running on my Xperia but the voice is terrible. Too computerized and annoying.

Does anyone know of any alternative hopefully English sounding voices or alternatively cheap or free sat navs worth using instead

Nav free seems decent. Can't stand the android voices.
