Binaural intelligibility prediction based on the speech transmission index
The Journal of the Acoustical Society of America, 2008Although the speech transmission index (STI) is a well-accepted and standardized method for objective prediction of speech intelligibility in a wide range of environments and applications, it is essentially a monaural model. Advantages of binaural hearing in speech intelligibility are disregarded.

Speech Privacy Protection based on Controlling Estimated Speech Transmission Index
2020 17th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2020Speech transmission index (STI) is an objective measurement of speech transmission quality and is used to predict the speech intelligibility. STI is also highly related with listening difficulty and is a function of room impulse response (RIR). RIR is regarded as the transfer function between the sound source and the sound receiver, and is generally ...

As well as background noise and the acoustic conditions of the given space, speech intelligibility (SI) is affected by the binaural effect (BE), which is sensitive to the head orientation (HO) of the listener, especially in a small enclosed space such as an automobile.

Uncertainties in speech transmission index measurements
The Journal of the Acoustical Society of America, 2014A detailed study has been carried out into the uncertainties associated with Speech Transmission Index (STI) measurements. The uncertainties and measurement errors are shown to be either systematic or random in nature. Systematic errors were found to include limitations of the technique itself as well as uncertainties related to measurement hardware ...

Influence of impulse noise on speech transmission index
The Journal of the Acoustical Society of America, 1995This paper analyzes the influence of impulse noise impairments in a telecommunication channel on the speech transmission index (STI) value, which was measured using RASTI method. So far STI has not been applied in telecommunications as a speech transmission quality measure. Impulse noise components were formed as IEEE standard impulse streams.

The present article is divided into four major sections dealing with the application of acoustical indices to the prediction of speech recognition performance. In the first section, two acoustical indices, the Articulation Index (AI) and the Speech Transmission Index (STI), are described.

Computation of modulation spectra for the speech transmission index using real speech
Proceedings of IEEE Workshop on Applications of Signal Processing to Audio and Acoustics, 2002While it has been suggested that the speech transmission index (STI) for on environment may be calculated using speech rather than test signals, computational artifacts distort the speech analyses whereas they have minimal impact on analyses with test signals.

A modified objective model expanding on the speech-based speech transmission index is proposed to predict speech intelligibility under various conditions of nonlinear distortion. The proposed model computes values over a time window by analyzing the signal to noise ratio and the modulation transfer function between the input and output of a ...

Prediction of reverberation time and speech transmission index in long enclosures
The Journal of the Acoustical Society of America, 2005It is known that the sound field in a long space is not diffuse, and that the classic theory of room acoustics is not applicable. A theoretical model is developed for the prediction of reverberation time and speech transmission index in rectangular long enclosures, such as corridors and train stations, where the acoustic quality is important for speech.

The speech transmission index (STI) is the most widely used objective metric for speech intelligibility evaluation in enclosed spaces. STI thresholds specify the minimum values needed for specific intelligibility levels and serve as the basis for relevant room-acoustics standards.
