A waveform analysis of speech is disclosed. Embodiments include methods for analyzing captured sounds produced by animals, such as human vowel sounds, and accurately determining the sound produced. Some embodiments utilize computer processing to identify the location of the sound within a waveform, select a particular time within the sound, and measure a fundamental frequency and one or more formants at the particular time. Embodiments compare the fundamental frequency and the one or more formants to known thresholds and multiples of the fundamental frequency, such as by a computer-run algorithm. The results of this comparison identify of the sound with a high degree of accuracy.
A system for identifying a spoken sound in audio data, comprising a processor and a memory in communication with the processor, the memory storing programming instructions executable by the processor to:
A method, comprising:
The system of claim 26, wherein said determining includes comparing the misperceived sounds to the ranges listed in claim 43 until F1/F0, F1, F2 and F3 match a set of ranges correlating to at least one vowel or all ranges have been compared.
