A speech corpus (or spoken corpus) is a database of speech audio files and text transcriptions. In speech technology, speech corpora are used, among other things, to create acoustic models (which can then be used with a speech recognition or speaker identification engine). In linguistics, spoken corpora are used to do research into phonetic, conversation analysis, dialectology and other fields.
A corpus is one such database. Corpora is the plural of corpus (i.e. it is many such databases).
There are two types of Speech Corpora:
- Read Speech – which includes:
- Book excerpts
- Broadcast news
- Lists of words
- Sequences of numbers
- Spontaneous Speech – which includes:
- Dialogs – between two or more people (includes meetings; one such corpus is the KEC);
- Narratives – a person telling a story (one such corpus is the Buckeye Corpus);
- Map-tasks – one person explains a route on a map to another;
- Appointment-tasks – two people try to find a common meeting time based on individual schedules.
A special kind of speech corpora are non-native speech databases that contain speech with foreign accent.
