(Main)Speech and multimedia Transmission Quality (STQ) - Speech quality performance in the presence of background noise - Part 1: Background noise simulation technique and background noise database
Speech and multimedia Transmission Quality (STQ) - Speech quality performance in the presence of background noise - Part 1: Background noise simulation technique and background noise database
The quality of background noise transmission is an important factor, which significantly contributes to the perceived
overall quality of speech. Both existing and, even more notably, the new generation of terminals, networks and system
configurations, including broadband services, can be greatly improved when designed properly, with consideration and
presence of background noise. The present document:
• describes a noise simulation environment using realistic background noise scenarios for laboratory use;
• contains a database including the relevant background noise samples for subjective and objective evaluation.
The present document provides information about the recording techniques needed for background noise recordings and
discusses the advantages and drawbacks of existing methods. Additionally, the present document describes the
requirements for laboratory conditions. The loudspeaker setup and the loudspeaker calibration and equalization
procedure are described. The simulation environment specified can be used for the evaluation and optimization of
terminals and of complex configurations including terminals, networks and other configurations. The main application
areas should be: office, home and car environment.
The setup and database as described in the present document are applicable for:
• Objective performance evaluation of terminals in different (simulated) background noise environments.
• Speech processing evaluation by using the pre-processed speech signal in the presence of background noise,
recorded by a terminal.
• Subjective evaluation of terminals by performing conversational tests, specific double talk tests or talking and
listening tests in the presence of background noise.
• Subjective evaluation in third party listening tests by recording the speech samples of terminals in the presence
of background noise.
Kakovost prenosa govora in večpredstavnih vsebin (STQ) - Kakovost govora v prisotnosti šuma ozadja - 1. del: Simulacijska tehnika šuma ozadja in podatkovna zbirka šumov ozadja
Kakovost prenosa šuma ozadja je pomemben dejavnik, ki bistveno prispeva k sprejeti celotni kakovosti govora. Obstoječo in še toliko bolj novejšo generacijo terminalov, omrežij in konfiguracij sistemov, vključno s širokopasovnimi storitvami, je mogoče znatno izboljšati s pravilnim projektiranjem, ob upoštevanju in obravnavi prisotnosti šumov ozadja. Ta dokument:
• vsebuje opis okolja za simulacijo šuma, v katerem so uporabljeni realistični scenariji za šum ozadja za laboratorijsko uporabo;
• vsebuje zbirko podatkov, vključno z relevantnimi vzorci šuma ozadja za subjektivno in objektivno vrednotenje.
V tem dokumentu so podane informacije o tehnikah zapisovanja, ki so potrebne za zapisovanje šuma ozadja, ter obravnavane so prednosti in pomanjkljivosti obstoječih metod. V tem dokumentu so prav tako opisane zahteve za laboratorijske pogoje. Opisani so postopki nastavljanja zvočnikov ter umerjanja zvočnikov in izenačevanja temperature. Določeno simulacijsko okolje je mogoče uporabiti za vrednotenje in optimizacijo terminalov ter zapletenih konfiguracij, vključno s terminali, omrežji in drugimi konfiguracijami. Glavna območja uporabe naj so: pisarna, domače okolje in avtomobil.
Namestitev in zbirka podatkov, kot sta opisani v tem dokumentu, se uporabljata za naslednje:
• objektivno vrednotenje delovanja terminalov v različnih (simuliranih) okoljih s šumom ozadja;
• vrednotenje obdelave govora s predhodno obdelanim govornim signalom ob prisotnosti šuma ozadja, ki ga zabeleži terminal;
• subjektivno vrednotenje terminalov na podlagi izvedbe pogovornih preskusov, specifičnih preskusov dvojnih prenosov ali preskusov oddajanja in prejemanja ob prisotnosti šuma ozadja;
• subjektivno vrednotenje preskusov prejemanja tretjih oseb z zapisovanjem vzorcev govora terminalov ob prisotnosti šuma ozadja.
