About This Item
Full Description
- 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 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.
