A Method to Determine the Speech Transmission Index From Speech Waveforms
Journal of the Acoustical Society of America, 1999A method for computing the speech transmission index (STI) using real speech stimuli is presented and evaluated. The method reduces the effects of some of the artifacts that can be encountered when speech waveforms are used as probe stimuli. Speech-based STIs are computed for conversational and clearly articulated speech in several noisy, reverberant ...

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.

A New Verification of the Speech Transmission Index for the English Language
Speech Communication, 2018Abstract The speech transmission index (STI) is one of the most widely used and standardized methods for objective prediction of speech intelligibility of transmission channels. The original verification of the relationship between the STI and the intelligibility for the English language was published in 1987.

The Speech Transmission Index (STI) is a physical metric that is well correlated with the intelligibility of speech degraded by additive noise and reverberation. The traditional STI uses modulated noise as a probe signal and is valid for assessing degradations that result from linear operations on the speech signal. Researchers have attempted to extend

Accuracy of Evaluation of Speech Transmission Index With Formant-Modulation Method
Radioelectronics and Communications Systems, 2023Unlike the known modulation method, the formant-modulation method for the evaluation of speech intelligibility allows the evaluation of not only the speech transmission index but also the articulation index. This paper presents the results of a study of the accuracy of speech transmission index evaluation using the full and rapid variants of the ...

, 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.

Based on simulated monaural and binaural room impulse responses, the relationship between Chinese speech intelligibility scores and speech transmission index (STI) including the effect of noise is investigated using a phonetically balanced test in virtual rooms. The results show that Chinese speech intelligibility scores increase monotonically with STI

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.

, 2010 An objective measure of speech intelligibility is required in order to guess whether or not the written transcription made from an intercept recording is an accurate representation of the talker's speech or if it is influenced by the views of the transcribers.
