A spontaneous reaction is a reaction that favors the formation of products at the conditions under which the reaction is occurring. A roaring bonfire is an example of a spontaneous reaction. A fire is exothermic, which means a decrease in the energy of the system as energy is released to the surroundings as heat. The products of a fire are composed mostly of gases such as carbon dioxide and water vapor, so the entropy of the system increases during most combustion reactions. This combination of a decrease in energy and an increase in entropy means that combustion reactions occur spontaneously.

When speech understanding systems are used in real applications, they will have to deal with phenomena peculiar to spontaneous speech. People use language differently when they speak than when they write. Spoken language contains many interjections, filled pauses, etc. Speakers often don’t use well-formed sentences. They speak in phrases, have restarts, etc. Systems designed for written or read text will encounter serious difficulties processing such input.
