This paper focuses on an approach to improve automatic phonetic transcription of proper nouns. The method is based on a two-level iterative process that extract the phonetic variants from the audio signals before filtering the irrelevant variants. The evaluation of the method shows a decreasing of the Word Error Rate (WER) on segments of speech with proper nouns, without affecting negatively the WER on the rest of the corpus (ESTER corpus of French broadcast news).
