Abstract
In speech retrieval, text queries are matched to spoken-word
recordings.
We undertook a series of retrieval experiments on such speech
documents, using both phonemes and words for matching text to speech.
We found that, given a reliable automatic word-based process for
speech recognition, phoneme-based retrieval
can be as effective as word-based retrieval.
However, retrieval is worse with phoneme-based speech recognition.
Error correction techniques, such as manual error correction of
phoneme sequences and use of a standard string edit distance, did not
improve the effectiveness of phoneme-based retrieval.
