A robot voice typically refers to any type of audio signal that is produced to sound like human speech, but is generated by a computer system. This can be accomplished in a number of different ways, including the creation of an archive of spoken words or sounds that are then properly assembled by a computer. A robot voice is often used with automated computer systems, which can include full recorded messages as well as custom responses to human feedback. Modulation or alteration of a voice can also be performed by someone using a computer to allow original human audio to sound computerized.
The term “robot voice” is often used in a general way to refer to just about any type of speech that is generated or altered by an electrical or computer system. These voices may, in fact, have absolutely nothing to do with an actual robot, and so the term can be something of a misnomer. There are a number of different software programs and websites that can be used to generate a robot voice, often based on text that is typed in by a user. This text is then used to indicate to a system what pieces of recorded audio should be used and assembled together to create a voice response.
It is also possible for a robot voice to be created in a completely digitized way, without any initial human voice recordings. This type of audio can be produced through the creation of audio signals that resemble different words or units of language that are often produced during human speech. By assembling these sounds together in an appropriate way, it all comes together to create words in a robot voice. Such voices are often considered a staple of science-fiction works from the past, and the reality of modern Artificial Intelligence (AI) systems would allow for robots with much more humanoid voices.
A robot voice can also be produced through heavy modulation and changing of a recorded or real-time audio sample from a person. This does not necessarily take individual pieces of language and assemble them together, but instead simply changes the original sounds to seem electronic or robotic. Audio recordings can be changed through various pieces of hardware and with programs to resemble a robot voice, often through modulation and a change in the audio to a lower pitch. There are also devices that can be used to change a person’s voice in real time, by speaking into a microphone and then relaying the altered voice through a speaker.
