According to the classification of text types, the Reiss introduces an audio-media type to cover the rising of translation and separate this kind of translation besides sticking the conventional three based on Buhler’s functions of the linguistic sign.

In the Reiss’s later work, Translation assessment, she claims that linguistic translation has a long history no shorter than human history. She also suggests that it is clever to have critical thinking in translation not only now but in future since there have been always criticism of translating. Simultaneously, Reiss points out the challenges faced by todays’ translators that the areas of translation expands faster and wider than ever, which result in a enormous need of translation materials that include not only “literary texts” but also “pragmatic texts” in the translation theory research. To deal with such huge amount of translation materials, Reiss insists that it is still necessary to find out hitherto unknown cross-relationship or make overlooked associations clearer till now, which would contribute to make translation problems systematic, translation teachable and assessment of translation more objective. To achieve this, Reiss suggests
