Using a voice that is highly pleasing to the ear, a delightful voice, can probably open more doors to an audience than any other. That is why such a voice should be among the first to consider, almost for any purpose.
Sometimes, the form dominates over the content. Still, if the two are in a good balance, the effect is even more potent. During the times when radio dominated the world of news, programes or commercials, a delightful voice was always the element that tipped the scales. So many shows and programs were extremely popular just because of the vocal qualities of a presenter.
Even with the advent of the TV and currently in the era of video streaming, a delightful voice attracts additional attention to the content that is put in fron of an audience. This is particularly true for the commercially geared content, the one that needs to reach as many potential customers as possible. A delightful voice is that element that strengthens the message and gives it an additional quality. Of course, the use of such a voice is not limited to just commercial purposes, but can be used in a wide range of messages. It has a particular impact in late night shows, whether it is 'standard' radio, TV or streaming podcasts.
While what constitutes a delightful voice is mainly in the ear of the beholder, there are certain general qualities that are universally accepted by most listeners. A delightful voice has, what is called a 'silky 'quality, tonality that is usually in the midgrange. It has a specific vocal color, and is a voice that usually speaks at a slower or a medium pace.
