The archive audio track is converted to text by means of the ASR method. The query (Qs) is searched in the indexed text form. The searched query (Qs) is expanded by a sequence of phonemes, homophones, synonyms and alternative forms in another language. Said query is expanded by means of the phonetic transcription (PT), the phonetic dictionary (PD), the thesaurus (TH), and the translator (TR). The output consists in expanded queries (Qw) which are filtered by means of the index dictionary (ID). The index dictionary (ID) filtration outputs serve as the input (IS) of the search engine (S) which searches them in indexed text forms of the audio-archive and all partial results (Os) are displayed to the user. The device contains the query-expansion (EQ) module and the search engine (S) module. These ones are interconnected mutually through the index dictionary (ID) and through the sub-word segmenter (SEG) if need be. The query-expansion (EQ) module is interconnected further with the phonetic transcription (PT) module, with the phonetic dictionary (PD) module, the thesaurus (TH) module, and with the translator (TR) module.
