Voice data collection is the process of gathering and measuring audio data from a variety of sources for marketing, qualitative research, in-car navigation systems, call centre data, free speech data, etc. The contemporary world technology is advancing from ‘touch’ as the primary user interface to a ‘new age of voice and digital assistants.’ Audiences now engage with search engines on a more advanced level and in more significant ways by using the power of their voice. However, while humans can process a wide variety of sounds, teaching a machine to understand and process audio input is quite challenging. To recognize human speech, virtual assistants need to be exposed to large quantities of high-quality audio data.
