How do I measure speech intelligibility with EASERA?

In EASERA almost any evaluation and measure can be derived directly or indirectly from loaded or measured impulse response data. The same is true for most of the intelligibility measures.

EASERA allows for calculating STI, STI (Male), STI (Female) as well as AlCons and the equivalent STIPa. Note that these values are all calculated from the modulation transfer function (MTF), which in turn originates in the impulse response.

Also a lot of other measures are supported, for example as referenced by ISO 3382, such as G, Definition, C50 and C80 or IACC. Additionally other important metrics have been made available, such as Support ST and many more.
