Subjective speech evaluation is the gold standard to assess speech quality of head and neck cancer patients. This study investigates if conventional acoustic-phonetic and novel feature analysis contribute to the development of a multidimensional speech assessment protocol. Speech recordings of 51 patients 6 months post-treatment and of 18 control speakers were subjectively evaluated for intelligibility, nasal resonance and articulation. Self-evaluation of speech problems was assessed by the EORTC QLQ-H&N35 speech subscale. Feature analysis was performed to assess objectively nasality in vowels /a,i,u/. Results revealed that size of the vowel triangle, pressure release of /k/ and nasality in /i/ predict best intelligibility, articulation and nasal resonance and differentiated best between patients and controls. Within patients, /k/ and /x/ differentiated tumour site and tumour classification. Various objective variables were related to speech problems as reported by patients.
