'Voice modulation' refers to the process of altering or modifying the characteristics of a person's voice using artificial intelligence (AI) algorithms and techniques. This technology can be used to change the pitch, tone, and other characteristics of a voice to create a different voice or to enhance the quality of the existing voice. Voice modulation technology is used in a variety of applications, including voiceovers, podcasts, and video content creation. AI-powered voice modulation tools can analyze and understand the characteristics of a person's voice, and then generate a modified voice that meets the desired outcome. Voice modulation technology can also be used for text-to-speech applications, where written text is converted into spoken language using a modified voice. Voice modulation technology has improved greatly in recent years, with more natural-sounding voices and the ability to express emotions through speech. However, there are still limitations and challenges to overcome, such as accurately capturing the nuances of a person's voice and creating a truly convincing modified voice.
