Speech and text corpora

Eight main differences between collections of written and spoken language data

• durability of text, volatility of speech;
• different production times for text and speech;
• correcting errors in the production of text and speech;
• orthographic identity and phonetic variability of lexicalised units;
• printable ASCII-strings and continuously sampled speech;
• size differences between NL and SL data;
• the different legal status of written texts and spoken words;
• the different nature of categories and time functions.
