A method for analysing acoustic parameters of speech to detect, diagnose, predict and/or monitor progression of a condition, disorder, or disease, the method comprising:
- receiving an audio stream containing speech data encoding at least one word spoken by an individual;
- converting the audio stream into a sound signal;
- extracting from the sound signal a first formant data set comprising formant frequencies associated with letters in the at least one word as the audio stream is being received in near real time without recording the speech data encoding the at least one word spoken by the individual;
- determining from the first formant data set formant frequencies that are associated with at least one or more vowel letter in the word;
- determining the at least one vowel letter from the determined formant frequencies;
- recording a second formant data set comprising at least some of the determined formant frequencies for the at least one vowel letter;
- generating score data by applying at least one predetermined acoustic metric to the second formant data set, in which the score data is used to determine a level of articulation of the at least one vowel letter in the at least one word spoken by the individual, and
- storing the score data as an output file.
