Speech Communication, 2007
The speech intelligibility in rooms is evaluated using the room impulse responses obtained from the room acoustical simulation software ODEON. The simulated room impulse responses are first convolved with the speech intelligibility test signals recorded in an anechoic chamber, then reproduced through the earphone.

2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012
A new speech intelligibility metric is proposed for the assessment of speech enhancement processors. These processors usually affect the fine structure in speech that is of fundamental importance to speech intelligibility. Classical metrics analyze the entire signal and thereby generally overestimate intelligibility.

Objective measurement of the speech transmission quality of vocoders by means of the Speech Transmission Index [PDF]
, 2005 Nearly all types of military speech communication involve the use of so-called (narrow band) voice coders or vocoders. Usually the Speech Transmission Index (STI) uses artificial test signals, which can not be reproduced by vocoders with the usual fidelity. Therefore the STI is not able to evaluate vocoders at this time.

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.

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.

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.

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.

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.

Using the Speech Transmission Index for predicting non-native speech intelligibility
The Journal of the Acoustical Society of America, 2004While the Speech Transmission Index (STI) is widely applied for prediction of speech intelligibility in room acoustics and telecommunication engineering, it is unclear how to interpret STI values when non-native talkers or listeners are involved.
