The terms speaker dependent and speaker independent need to be clarified:

• speaker dependent: each word to be recognised is only compared with words spoken by the same speaker.
• for the purposes of this assignment, the term speaker independent has been given two meanings,
  1. each word to be recognised is compared with all the words available; ie words spoken both by the speaker of the test word and the other speakers.
  2. each word to be recognised is compared with all the words spoken by different speakers; ie words spoken by the speaker of the test word are not used in the recognition process. This implies that the speaker is totally unknown to the system and as such the system has to estimate a word to its best ability using data from other speakers.
