Code of Practice

This is the current IAFPA Code of Practice which was approved by the AGM in Helsinki, 2004.

  1. Members should act in all circumstances with integrity, fairness and impartiality.
  2. Recognising the varied array of casework subsumed under the interests of IAFPA (eg speaker identification/elimination, speaker profiling, voice line-ups, transcription, authentication, signal enhancement, sound propagation at crime scenes), Members should maintain awareness of the limits of their knowledge and competencies when agreeing to carry out work.
  3. Members should not enter into any arrangements in which remuneration is dependent on the outcome of the case.
  4. Members should make clear, both in their reports and in giving evidence in court, the limitations of forensic phonetic and acoustic analysis.
  5. In reporting on cases where an opinion or conclusion is required, Members should make clear their level of certainty and give an indication of where their conclusion lies in relation to the range of judgements they are prepared to give.
  6. (a) Members should exercise particular caution if carrying out forensic analysis of any kind on recordings containing speech in languages of which they are not native speakers.
    (b) In carrying out forensic speaker identification/elimination work, Members should exercise particular caution if the samples for comparison are in different languages.
    (c) Members should exercise particular caution if carrying out authenticity or integrity examinations of recordings that are not claimed to be original.
  7. Members undertaking forensic phonetic and acoustic analyses or operations of all kinds should state in their reports the methods they have followed and provide details of the equipment and computer programs used.
  8. Members, in making their analysis, should take due account of the methods available at the time and of their appropriateness to the samples under examination.
  9. Members should not attempt to do psychological profiles or assessments of the sincerity of speakers.
  10. Members' reports should not include or exclude any material which has been suggested by others (in particular by those instructing them) unless that Member has formed an independent view.
