Real-Time Control of an Articulatory-Based Speech Synthesizer for Brain Computer Interfaces
Fig 6
Subjective evaluation of the intelligibility of the speech synthesizer (offline reference synthesis).
A–Recognition accuracy for vowels and consonants for each of the 5 synthesis conditions. The dashed lines show the chance level for vowels (blue) and VCVs (orange). B–Recognition accuracy of the VCVs regarding the vocalic context, for the 5 synthesis conditions. The dashed line shows the chance level. C–Recognition accuracy of the consonant of the VCVs, for the 5 synthesis conditions. Dashed line shows the chance level. See text for statistical comparison results.
