Raspy voice has been thought as sexy, in particular with legendary singers like Rod Stewart and Brian Adams. It may be the signature voice for them, but definitely not something you want to develop.
Raspy voice is the reflection of vocal damage, as the result of improper voice projection. It could be due to shouting too much, speaking for too long without proper rest, lowering your voice too often, or still trying to speak when you run out of breath (this is called vocal fry). All lead to too much strength on the vocal cords and create potential damages as vocal nodes, polyps, etc.
Surely you can take surgery if you ever have vocal damage, but that may be the last resort. The vocal cords are so delicate. Watch these videos and you’ll probably think not twice but twelve times!
The best way is to shift your strength in projection from vocal cords to diaphragmatic region. Once you are able to do that, you’ll never find difficulty in projecting your voice, lose your voice or experience vocal damage.
