In this chapter we will try to discover the importance of audio and voice as key elements in building a personal brand. Podcast, audioblogs and web tools that reference the sound will be analyzed based on their degree of influence on personal branding. By using the voice we can differentiate ourselves from our competitors, so the audio branding, or sonic branding as it is also known, shows a verbal identity of his own personality. The sound has always been known for being a great tool to convey memorable messages to consumers, in fact we are able to consume the sound since we are in the womb. Having an audio brand is one way to ensure that no other company uses a similar audio and make our brand is consistent. The radio language, consisting of voice, music, silence and the special effects are responsible for generating emotions in the receiving public. The audio conveys information, entertains consumers and in the long term, helps build a positive image that reinforces the brand values. The design of an audio brand goes beyond creating a catchy jingle or a piece of melody.
