We convert a proposed search term to a feature representation and then use these features to predict the reliability of a search term. Key factors include the number of syllables in the word and the phonetic content.
  14. (MOBILE | Started: 2002 | Status: Completed | Sponsor: Mississippi State University) MOBILE COMPUTING USABILITY: Increasingly smaller and more complex computing devices have made the human interface to these systems more critical than ever.

  18. (NSF_ITR | Started: 2000 | Status: Completed | Sponsor: National Science Foundation) SPOKEN LANGUAGE INFORMATION RETRIEVAL: Integration of prosodic information, speech recognition and parsing can positively impact the problem of information extraction from spoken documents.

  19. (NSF_NONLINEAR | Started: 2004 | Status: Completed | Sponsor: National Science Foundation) NONLINEAR STATISTICAL MODELING OF SPEECH: Hidden Markov models (HMMs) have been the primary approach to speech recognition many years. The goal of this project was the development of a new approach to statistical modeling of speech based on nonlinear statistics. We implemented a speaker recognition system using a variety of nonlinear models including linear dynamic models and probabilistic mixtures of autoregressive models.
  20. (POWERTRAINS | Started: 2003 | Status: Completed | Sponsor: Mississippi Stte University) POWERTRAIN DESIGN AND OPTIMIZATION: State of the art design tools in automotive engineering lacks the power, sophistication, and automation of design tools for the electronics industry. We fundamentally advanced automotive design engineering by introducing optimization and physics-based design principles into standard industry design tools. This allowed designers to globally optimize design criteria such as size, efficiency, cost, weight, volume, and achieve unprecedented reductions in design turnaround time.
  21. (ROBUST_ACOUSTIC | Started: 2004 | Status: Completed | Sponsor: Conversay, Inc.) ROBUST ACOUSTIC MODELING: Field deployment of speech recognition technology results in a number of interesting problems, such as microphone saturation, which severely limit the performance of speech recognition engines. In this project, we studied the effects of microphone saturation and develop algorithms to improve robustness to saturation, clipping, and other forms of signal degradation.
  22. (ROBUST_LOW_PERPLEXITY | Started: 1998 | Status: Completed | Sponsor: MITRE) ROBUST LOW PERPLEXITY VOICE INTERFACES: Robust speech recognition technology for speech recorded and transmitted over narrowband channels requires advances in several components of a speech recognition system: signal processing techniques that produce invariant feature sets; acoustic modeling and training that produce channel-independent acoustic models; noise cancellation techniques that mitigate the effects of impulsive and application-dependent transient noise. This project was a one-year collaboration with the MITRE Corporation that resulted in a prototype of a near real-time system that provided a robust and flexible command and control voice interface in realistic tactical noisy environments.
  23. (SOUTHERN_ACCENTS | Started: 2000 | Status: Completed | Sponsor: Dragon) SOUTHERN-ACCENTED SPEECH: Southern accents are underrepresented in most pubicly available databases. This had led to speculation that performance for such speakers is worse than other better-represented dialects. To test this hypothesis, a small data collection effort was conducted that targeted Southern-accented speakers. Data was collected from February 21 to February 25, 2000. The data collected consisted of a total of 23 speakers (13 males and 10 females) ranging in age from 18 to 56.
  24. (SPEECH | Started: 1998 | Status: Completed | Sponsor: National Science Foundation) INTERNET-ACCESSIBLE SPEECH RECOGNITION TECHNOLOGY: Speech recognition research has always been a core competency in ISIP. Large vocabulary conversational speech recognition LVCSR) is a fascinating technology that draws heavily from the diverse research areas of statistical pattern recognition, digital signal processing, artificial intelligence, linguistics, and information theory. On this web site you will find a powerful and flexible public domain speech recognition system written in C++.
  25. (SUMMER_OF_CODE | Started: 2010 | Status: Completed | Sponsor: Temple University) SUMMER OF CODE: RESEARCH EXPERIENCE FOR UNDERGRADUATES: Every summer we welcome a group of enthusiastic undergraduates into our lab with a goal of developing their software skills and introducing them to fields such as speech and EEG signal processing, machine learning and big data.
  26. (SWITCHBOARD | Started: 1998 | Status: Completed | Sponsor: DoD) SWITCHBOARD RESEGMENTATION: The SWITCHBOARD Corpus (SWB) has become critical to the success of state-of-the-art LVCSR systems. Using this data, however, has not been without its share of drawbacks. Word-level transcription of SWB is difficult, and conventions associated with such transcriptions are highly controversial and often application dependent. By 1998, the quality of the SWB transcriptions for LVCSR was recognized to be less than ideal, and many years of small projects attempting to correct the transcriptions had taken their toll. In February of 1998 ISIP began a project to do a final cleanup of the SWB Corpus, and to organize and integrate all existing resources related to the data into this final release.
  27. (T1_INTERFACE | Started: 1995 | Status: Completed | Sponsor: LDC) A DIGITAL TELEPHONE INTERFACE FOR SUN WORKSTATIONS: Using the Linkon system, a speech data collection board, we developed a fully-expandable, robust system for platform-independent collection of telephone speech data. Our object-oriented software libraries and intuitive GUI provide powerful tools with which even a novice user can efficiently prototype complex applications. Using the system one can generate programs which range from simple single-user prompt/record demonstrations to robust SWITCHBOARD-type multi-user applications.
  28. (USFS | Started: 1996 | Status: Completed | Sponsor: USFS) SCENIC BEAUTY ESTIMATION OF FORESTRY IMAGES: The United States Department of Agriculture and Forest Services requested we develop an algorithm to automatically determine the scenic beauty of a given forest scene. Their requirement is a consequence of rising public concern to preserve forest beauty. To achieve this, we have developed an extensive database that can support our algorithm development. The database consists of 637 unique images, each image having various subjective ratings for their scenic beauty content. The database extensively samples several dimensions of the problem including year, season, time of day, angle and treatment. In order to automatically relate the beauty of an image to the subjective beauty ratings, we developed algorithms to extract features from the image that determine its scenic beauty.
  29. (VOICE_ANALYSIS | Started: 2003 | Status: Completed | Sponsor: Creare, Inc.) COGNITIVE ASSESSMENT USING VOICE ANALYSIS: The goal of this project was to design an effective fatigue monitoring and assessment system by characterizing changes in a human voice as a speaker becomes fatigued or stressed. A remote, near-real-time assessment system to monitor the fatigue levels of military personnel was developed.
  30. (VPMS | Started: 2004 | Status: Completed | Sponsor: Mississippi State University) VEHICLE PERFORMANCE MONITORING SYSTEM: This project is a one-year collaboration with the Mississippi Department of Transportation (MDOT) to adapt and apply the Mississippi State University wireless web-based vehicle performance and monitoring system (VPMS).
  31. (WE2 | Started: 2014 | Status: Completed | Sponsor: National Science Foundation) BRAINWAVE RECOGNITION: This project is a half-day laboratory on brainwave recognition that includes an introduction to Python.
