Journal of Sound and Vibration, 2004
Classrooms, especially those related to the early development of individuals, are very important nowadays as they play a crucial role in the development of human characters and the attitude towards learning, both of which eventually define whether or not an individual will have a successful life.

The Journal of the Acoustical Society of America, 2006
During the acoustical design of, e.g., auditoria or open-plan offices, it is important to know how speech can be perceived in various parts of the room. Different objective methods have been developed to measure and predict speech intelligibility, and these have been extensively used in various spaces. In this study, two such methods were compared, the

Development of a binaural speech transmission index
The Journal of the Acoustical Society of America, 2006Although 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 to the intelligibility of speech are disregarded.

Speech Degradation as Measured by the Rapid Speech Transmission Index (RASTI)
Ear and Hearing, 1991This study demonstrates degradation of a modulated speech-like signal in a typical listening environment as measured by the new Bruel and Kjaer Rapid Speech Transmission Index (RASTI) System. Thirty-four adults were seated in a typical college classroom. Measurements of the RASTI signal were made at 17 different seating locations.

Blind Estimation of the Speech Transmission Index for Speech Quality Prediction
2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018The speech transmission index (STI) of a listening position within a given room indicates the quality and intelligibility of speech uttered in that room. The measure is very reliable for predicting speech intelligibility in many room conditions but requires an STI measurement of the impulse response for the room.

Further Validation of the Speech Transmission Index (STI)
Journal of Speech, Language, and Hearing Research, 1987The present article further evaluates the accuracy of speech-recognition predictions made according to two forms of the Speech Transmission Index (STI) for normal-hearing listeners. The first portion of this article describes the application of the modified Speech Transmission Index (mSTI) to an extensive set of speech-recognition data.

New directions for a speech-based speech transmission index
The Journal of the Acoustical Society of America, 2006The standardized method for determining the speech transmission index (STI) involves the use of a specific intensity-modulated test signal. The STI is obtained from measurements on the transmission channel, usually showing reductions of the modulation depths in the received test signal.

Applied Acoustics, 2019 Everyday communication takes place in the combined presence of reverberation and background noise, the latter having in some cases fluctuating characteristics and speech-like spectrum. To predict the speech intelligibility for fluctuating maskers, a time-

Using the Speech Transmission Index to predict the intelligibility of non-native speech
The Journal of the Acoustical Society of America, 2002The calibration of the Speech Transmission Index (STI) is based on native speech, presented to native listeners. This means that the STI predicts speech intelligibility under the implicit assumption of fully native communication. In order to assess effects of both non-native production and non-native perception of speech, the intelligibility of short ...
