In today’s date, logging & interpreting a voiceprint by the means of the severity, roughness, pitch, loudness, etc. of the sounds created by a person while speaking is crucial, primarily for criminal investigations and military intelligence objectives. Every person’s voice is different because the structure or make-up of the vocal cords, verbal cavity, oral and nasal openings is unique to each.
Voice Forensics & Keyword Detection – What is it?
Voice Forensics is a scientific analysis which incorporates evaluation, filtering, and authenticating voice recordings for the purpose of an inquiry or trial. Further, to investigate ahead on the above-mentioned, one needs to have an effectual voice biometrics program. A technique which analyzes audio evidence accurately by implementing voice recognition technology in a way that makes it easier to function with the gathered audio evidence. This would indeed aid forensic specialists as well as security-oriented companies to finalize voice treatment and speaker recognition practices precisely.
While keyword detection is a sub function of the voice recognition technology that detects the existence of a word or concise phrase within a specified stream of audio, the most common use case of keyword detection is voice activation of virtual assistants. For example, “Hey Alexa” is the keyword for the Alexa assistant. Upon identification of the keyword, a scenario-oriented action is carried out.
How does Keyword Detection work?
Keyword Detection uses speech recognition to identify an organization’s target keywords and phrases. Keywords can be customized as per specific needs and preferences. Specific desired phrases or words can be chosen to act as triggers with the appropriate action to be taken once identified. The calls and recordings are then constantly monitored, which provides you the ability to evaluate them as early as they get spotted.
