There are potential advantages to having your recordings transcribed verbatim. This means every additional detail is included word-for-word and never paraphrased, even including non-verbal sounds where possible.
Although this usually makes the text more difficult to scan through quickly, it can be invaluable if you want to interpret meaning from the subtler nuances of the dialogue. Stuttering, unintentional repetition, pauses and so on can be identified and analysed using this method.
This is especially useful for transcriptions of conversations with complicated or emotional circumstances involved, where the emotional responses of interviewees may not be communicated clearly in an abbreviated form. In a typical workplace, disciplinary meetings are a common example.
