Can you find someone by their voice?
Each human being has a voice that is distinct and different from everyone else’s. So it seems intuitive that we’d be able to identify someone from their voice fairly easily. These studies have found that we can actually recognise voices of familiar people’s speech quite well.
Can voice recognition be used in court?
Many cases in which voice identification is used as evidence, however, involve the identification of a stranger’s voice. In such cases, when a suspect has come to light, a voice lineup may be played for the witness, usually in the form of a tape-recorded series of short clips of several parties speaking.
Is digital recording the same as speech recognition?
There is a difference between digital dictation and voice recognition. Digital dictation merely records the voice in a digital mode as opposed to on an analogue tape recorder. Dictation is transitioning from a tape analogue system to a digital dictation system because of greater flexibility and ease of use.
How does voice recognition work on a phone?
Voice recognition (or speech recognition) allows you to rapidly write text just by speaking to your phone. For best results it will require an Internet connection. Accuracy varies depending on your accent, how fast you speak, surrounding noise levels and the subject nature (it may struggle with technical words or people’s names).
Are there any privacy issues with voice recognition?
While using speech for speaker recognition, such as the owner of a car or mobile phone, presents only minor privacy problems (the typical question here is: is this the same person?), the use for identification purposes (typically, the question here is: who is this person?) is a very different story.
What kind of Internet connection do you need for voice recognition?
For best results it will require an Internet connection. Accuracy varies depending on your accent, how fast you speak, surrounding noise levels and the subject nature (it may struggle with technical words or people’s names). Over 90% accuracy is common but you will need to edit the mistaken words using the keyboard.
How is speech recognition used to identify people?
The recognition software has been fuelled by massive sets of vocal data built into a huge model of how people speak. This allows measurements of how much a person’s voice deviates from that of the overall population, which is the key to verifying a person’s identity.
