I-vector speaker verification based on phonetic information under transmission channel effects
Past studies have shown evidence of important speakerspecific content in the higher frequencies of the spectrum, which are filtered out by narrowband channels. Besides, wideband transmissions, which are gaining ground over narrowband communications, offer an extended range of frequencies which account not only for better speech quality and intelligibility, but also for an improved speaker recognition performance. In this work, different phoneme classes (fricatives, nasals, and vowels) were...[Show more]
