Abstract: Occurrences of one or more keywords in audio data are identified using a speech recognizer employing a language model to derive a transcript of the keywords. The transcript is converted into a phoneme sequence. The phonemes of the phoneme sequence are mapped to the audio data to derive a time-aligned phoneme sequence that is searched for occurrences of keyword phoneme sequences corresponding to the phonemes of the keywords. Searching includes computing a confusion matrix. The language model used by the speech recognizer is adapted to keywords by increasing the likelihoods of the keywords in the language model. For each potential occurrences keywords detected, a corresponding subset of the audio data may be played back to an operator to confirm whether the potential occurrences correspond to actual occurrences of the keywords.

Abstract: The present invention relates to a synergistic formulation comprising trans-tetracos-15-enoic acid (t-TCA) and andrographolide (AP) in the ratio ranging between 1:7 to 7:1 (w/w), useful in hepatoprotection; and a process for the preparation of a synergistic formulation comprising trans-tetracos-15-enoic acid (t-TCA) and andrographolide (AP) useful in hepatoprotection, said process comprising steps of grounding the particles of the t-TCA and AP into fine particles, mixing the fine particles in ratio ranging between 1:7 to 7:1 (w/w), and grinding the mixture to obtain formulation, and also, a method of hepatoprotection of a subject using the synergistic formulation comprising trans-tetracos-15-enoic acid (t-TCA) and andrographolide (AP), said method comprising the steps of administering the formulation to the subject.

Abstract: A method and system for detecting certain types of content, such as advertisements, using acoustical means from a media stream. The method uses two matching processes to detect and identify repeated content, the starting and end boundaries of which are then found. This content is used as the basis to find non-repeated content (such as less-frequently repeated advertisements) that are typically located in proximity to repeated content and can be evaluated using Gaussian mixture models (GMMs). The system that implements this method can be used for advertisement detection and monitoring for traditional media, such as television and radio, as well as for Internet-based media, such as streaming video, streaming audio and podcasts. The system can also be used to detect and identify copyrighted material in Internet traffic.

Abstract: A method and an apparatus for adding a new entry to a speech recognition dictionary, and more particularly a system and method for generating transcriptions from multiple utterances and a textual representation of a given word is provided. The method and apparatus combine acoustic information obtained from each of the training utterances to generate the most likely transcriptions. It also provides a method and apparatus for transcribing multiple utterances into a single transcription that can be added to a speech recognition dictionary. In a first step, a graph representative of possible pronunciation of the word or combination of words is generated on the basis of the textual representation of the word and a letter to phoneme set of rules. Phonemes perceptually close to the phonemes in the transcriptions obtained using the letter to phoneme rules are added on parallel branches in the generated graph.
