The ability of human fetuses to recognize their own mother's voice was examined. Sixty term fetuses were assigned to one of two conditions during which they were exposed to a tape recording of their mother or a female stranger reading a passage. Voice stimuli were delivered through a loudspeaker held approximately 10 cm above the maternal abdomen and played at an average of 95 dB SPL. Each cond...

This working paper depicts the usage of Natural Language Processing techniques in the production of voice from an input text, a.k.a. Text-To-Speech synthesis, and the inverse process, which is the production of a written text transcription from an input voice utterance, a.k.a. Automatic Speech Recognition.

According to the source-filter model of speech production, speech can be represented by passing the excitation signal through the vocal tract filter. The epoch or instant of maximum excitation corresponds to the glottal closure instant. Several speech processing applications require robust epoch detection but this can be a difficult task. Although state-of-the-art epoch estimation methods can p...

This paper gives a brief overview of security using Biometrics Parameters. Security is one of the utmost requirements of homes and businesses which require multimodal biometric identification. This paper aims to identify a person through Voice and face recognition. The ARM based voice recognition module is used for voice recognition. Also some other techniques available for voice recognition ar...

From artificial voices in GPS to automatic systems of dictation, from voice-based identity verification to voice pathology detection, speech processing applications are nowadays omnipresent in our daily life. By offering solutions to companies seeking for efficiency enhancement with simultaneous cost saving, the market of speech technology is forecast to be particularly promising in the next ye...

Regions along the superior temporal sulci and in the anterior temporal lobes have been found to be involved in voice processing. It has even been argued that parts of the temporal cortices serve as voice-selective areas. Yet, evidence for voice-selective activation in the strict sense is still missing. The current fMRI study aimed at assessing the degree of voice-specific processing in differen...

Normal listeners effortlessly determine a person's gender by voice, but the cerebral mechanisms underlying this ability remain unclear. Here, we demonstrate 2 stages of cerebral processing during voice gender categorization. Using voice morphing along with an adaptation-optimized functional magnetic resonance imaging design, we found that secondary auditory cortex including the anterior part of...

OBJECTIVE To evaluate the vibration pattern of the substitute voice generator of patients who have undergone laryngectomy. For automatic quantification of the oscillations of the pharyngoesophageal (PE) segments, image processing of digital high-speed video sequences is applied. DESIGN Physiologic analysis. SETTING An acute care hospital. PATIENTS Endoscopic recordings were taken of 10 me...

This study aimed to evaluate the effects of auditory-verbal rehabilitation on voice parameters after implantation with cochlear implants 2 and 5 months after rehabilitation and compare them with normal voice children (under 12 years of age). A perceptive and electroacoustic evaluation of voice was carried out through a digital analysis after implantation and rehabilitation. The study was pe...
