Feedback on pronunciation or articulation is an important component of spoken language teaching. Automating this aspect with speech recognition technology has been an active area of research in the context of computer-aided language-learning systems. Well-known limitations in the accuracy of automatic speech recognition (ASR) systems pose challenges to the(More)
Dysarthria is a motor speech impairment, often characterized by speech that is generally indiscernible by human listeners. Assessment of the severity level of dysarthria provides an understanding of the patient's progression in the underlying cause and is essential for planning therapy, as well as improving automatic dysarthric speech recognition. In this(More)
Dysarthria is a motor speech disorder resulting from impairment in muscles responsible for speech production, often characterized by slurred or slow speech resulting in low intelligibility. With speech based applications such as voice biometrics and personal assistants gaining popularity, automatic recognition of dysarthric speech becomes imperative as a(More)
We present a visual aid for the hearing impaired to enable access to internet videos. The visual tool is in the form of a time synchronized lip movement corresponding to the speech in the video which is embedded in the original internet video. Conventionally, access to the audio or speech, in a video, by the hearing impaired is provided by means of either(More)
Interactive Voice Response (IVR) technology makes customer service 24 × 7 and cost effective and has been used by most customer facing enterprises. While effective, IVRs requires inputs to be keyed in using a touch tone phone, constraining the type of information that can be input. For this reason customers in general choose to speak with a human(More)
Robust phonetic segmentation is extremely important for several speech processing tasks such as phone level articulation analysis and error detection, speech synthesis, and annotation. In this paper, we present an unsupervised phonetic segmentation approach and its application to noisy and clipped speech such as mobile phone recordings. We propose a(More)
Through this paper, we present the Mobile Phone Assisted Remote Speech Therapy Platform for individuals with speech disabilities to avail the benefits of therapy remotely with minimal face-to-face sessions with the Speech Language Pathologist (SLP). The objetive is to address the skewed ratio of SLP to patients as well increase the efficacy of the therapy(More)
