Posted By Kieran J Duignan Alan Research in the field of speech and language therapy suggests that reliable occupational screening of the kind you apparently refer to is not yet possible on a general basis. Organic voice problems are the province of ENT specialists; referrals to them are normal before a SaLT conducts treatment, in case the presenting problem is a cancer. The growing consensus indicates that a large proportion of other complaints are 'psychogenic', or in plain language related to how the individual sees him/her-self, how he/she relates to others and manages sources of stress. Pre-screening on this basis involves psychological assessment; as there is a risk of rejection, you would need specialist assessment i.e. from a chartered psychologist with specialist training and experience in health ergonomics - which is likely to be very costly.
