The former can be achieved when the covariance matrix of the desired signal is rank deficient, which is the case, for example, for voiced speech.
The former case applies to signals that have a rank that can be assumed to be less than the rank of the observed signal covariance matrix, which is, for example, the case for voiced speech.
For example, thresholds for voice pitch discrimination and attribution of vocal masculinity (a trait associated with pitch) are not significantly different (Re, unpublished data).
If automatic speech recognition (ASR) is nonetheless required, for example for robust voice control in public spaces or for meeting transcription, the use of independent component analysis (ICA) can be important to segregate all involved speech sources for subsequent recognition.
Users request either a fixed minimum data rate, for example, as needed for voice services, or unconstrained best-effort (BE) data services.
As an illustrative example, we consider the NUM problem with Sigmoidal-like utility functions [30] that are used in many multimedia applications and Internet congestion control (for example, the utility for voice applications is modeled by a Sigmoidal function with a convex part at low rate and a concave part at high rate).
For some cancers of the head and neck, lung, cervix, bladder and prostate, radiotherapy can be used instead of surgery to achieve similar cure but with better functional results (for example, voice preservation for larynx cancers).
The detailed assessment covers the same areas as specified above but in greater depth for example, whispered voice test for hearing [ 17], Glasgow Acuity Cards for vision [ 18], Mini Mental State Examination for cognitive impairment [ 19], the Geriatric Depression Scale [ 20].
Certain actors had the task of voicing multiple roles; for example, the voice director was responsible for speaking the roles of Mrs Hew and Yah.
The goal, they argue, is to offer fewer distractions with built-in systems that use, for example, voice commands, buttons on the steering column and large touch screens.
