Doppler Passive Acoustic Mapping [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2020 In therapeutic ultrasound using microbubbles, it is essential to drive the microbubbles into the correct type of activity and the correct location to produce the desired biological response. Although passive acoustic mapping (PAM) is capable of locating where microbubble activities are generated, it is well known that microbubbles rapidly move within ...

Robust triphone mapping for acoustic modeling [PDF]
Interspeech 2012, 2012 In this paper we revisit the recently proposed triphone mapping as an alternative to decision tree state clustering. We generalize triphone mapping to Kullback-Leibler based hidden Markov models for acoustic modeling and propose a modified training ...

Review : Bathymetry Mapping Using Underwater Acoustic Technology
JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2019 The bathymetry mapping using underwater acoustic technology very important in Indonesia waters. Bathymetry is the result of measuring the height of the seabed so that the bathymetric map provides information about the seabed, where this information can ...

Compact representations of the articulatory-to-acoustic mapping [PDF]
Interspeech 2007, 2007 Articulatory codebooks are very often used to represent the articulatory-to-acoustic mapping. They thus need to be compact while offering a very good acoustic precision. This paper presents a method of articulatory codebook construction more general than that of Ouni in the sense that the articulatory-to-acoustic mapping is approximated by ...

Acoustic mapping of benthic sediments
, 2007 There is an increasing demand for knowledge of habitats, communities and distribution patterns of the seafloor for impact assessment, conservation and ecological studies. The European Union Water Framework directive will require a lot of effort to be met.

Feature Maps of the Acoustic Spectrum of the Voice [PDF]
Journal of Voice, 2020 The change in the spectrum of sustained /a/ vowels was mapped over the voice range from low to high fundamental frequency and low to high sound pressure level (SPL), in the form of the so-called voice range profile (VRP). In each interval of one semitone and one decibel, narrowband spectra were averaged both within and across subjects.

Discriminative map for acoustic model adaptation [PDF]
2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2003 In this paper we show how a discriminative objective function such as Maximum Mutual Information (MMI) can be combined with a prior distribution over the HMM parameters to give a discriminative Maximum A Posteriori (MAP) estimate for HMM training. The prior distribution can be based around the Maximum Likelihood (ML) parameter estimates, leading to a ...

Acoustic visualizations using surface mapping [PDF]
The Journal of the Acoustical Society of America, 2014 Sound visualizations have been an integral part of room acoustics studies for more than a century. As acoustic measurement techniques and knowledge of hearing evolve, acousticians need more intuitive ways to represent increasingly complex data. Microphone array processing now allows accurate measurement of spatio-temporal acoustic properties.

Mapping between acoustic and articulatory gestures
Speech Communication, 2011 This paper proposes a definition for articulatory as well as acoustic gestures along with a method to segment the measured articulatory trajectories and the acoustic waveform into gestures. Using an simultaneously recorded acoustic-articulatory database, the gestures are detected based on finding critical points in the utterance both in the acoustic ...
