Voice Recognition All Talk No Walk

Different types of Recogniton Speech Recognition What is being said Speaker Recognition Who is speaking Speaker Diarisation Voice Recognition (Combination) More accurate

Verification vs. Identification Verification, Comparing two samples 1:1 Also known as authentication Identification Comparing a sample to a database 1:N Used to identify with previous peoples Passport/Police Sketch analogy

Technology Just a microphone and computer Can be used over the phone

How Dis Software be Functionin Speaker Recognition Two Stippy Steps Enrollment Verification Takes characteristics from your voice to be compared later on

Speech Recognition frequency estimation hidden Markov models Gaussian mixture models pattern matching algorithms neural networks matrix representation Vector Quantization decision trees

Pros Non-Invasive Minimal Equipment Can be used over the phone Adaptable Versatile

Cons Easily fooled Changes in voice Aging Attitude changes
