The Santa Barbara Corpus of Spoken American English


The Santa Barbara Corpus includes c. 250,000 words of transcribed conversations from all over the U.S. It controls for a number of social variables, such as a speaker’s gender, age, hometown, education, occupation and ethnicity, making it useful for socio-linguistic research. The corpus also forms the main component of the spoken part of the the International Corpus of English U.S. (ICE-US). Sound files are available upon request.
The transcripts include precise time stamps and many indications of intonational properties. An example of a transcription is shown below:

The Switchboard Corpus


The Switchboard Corpus contains c. 260 hours, more than 2.5 million words, of transcribed telephone conversations. Participants were 543 speakers (302 male, 241 female) from all areas of the United States. A Second phase of the Switchboard Corpus added an additional c. 370 hours, or c. 4 million words, of telephone conversations by 679 speakers predominantly from the Midwest. A part of the corpus, called The Switchboard Dialog Act Corpus, comprising c. 1.4 million words, was made available for free in 2008.
The transcribers followed freely available guidelines. They foresee segmentation of speech into utterances, avoidance of punctuation, "non-speech sounds" such as [throat_clearing], and corrections of mispronunciations like "[splace/space]". An excerpt of a transcript is given below.
