The ideal binary mask is often seen as a goal for time-frequency masking algorithms trying to increase speech intelligibility, but the required availability of the unmixed signals makes it difficult to calculate the ideal binary mask in any real-life applications. In this paper we derive the theory and the requirements to enable calculations of the ideal binary mask using a directional system w...

We live in a world where there are countless interactions with computer systems in every-day situations. In the most ideal case, this interaction feels as familiar and as natural as the communication we experience with other humans. To this end, an ideal means of communication between a user and a computer system consists of audiovisual speech signals. Audiovisual text-to-speech technology allo...

This paper presents an automatic speech transformation method of non-ideal phonation of speech (irregular or creaky voice). The irregular-to-regular transformation is performed by analyzing and resynthesizing the residual. A recent continuous pitch estimation algorithm is used for interpolating F0 in regions of irregular voice. The linear prediction residual of irregular sections of speech is r...

Much of what we know about speech perception comes from laboratory studies with clean, canonical speech, ideal listeners and artificial tasks. But how do interlocutors manage to communicate effectively in the seemingly less-than-ideal conditions of everyday listening, which frequently involve trying to make sense of speech while listening in a non-native language, or in the presence of competin...

Elaborating one of the points of his Coling ~onn 1986 paper, the author discusses prononfn~lity, which is due to a special semantic stratum, singulatire identifieational deixis. Personal, reflexive and interrogative pronouns have additional transn[issional deictic markings, but singulative identificational pronominality alone has a direct anaphorie effect and tends to reinforce syntactically. T...

Rubrics as a measure of performance outcomes are nothing new to speech teachers. Evaluation of a clearly defined standard on a scale of descriptive criteria, which is then used to drive instruction, is the norm for the speech classroom. Kind of like with paradigms, the speech community has been quietly using performance rubrics apart from the frenzy of educational reform. However, the use of ru...

Single channel speech enhancement is necessary where the multichannel speech enhancement is not feasible due to space constraints in the intended device and cost-effectiveness. However, the problem of having limited information from single channel sound signal mixtures or unavailability of the speech source signals makes it more difficult to separate the target speech from the background masker...
