Expansion of the semantic coreThere are three main differences between voice search and traditional semantics.
Simple phrases. People approach writing a query in a search bar consciously: they try to choose specific and correct words. When they make a voice query, they express themselves in the same way as in everyday life. Therefore, for voice search, you need to choose the simplest verbal phrases.
The presence of a clearly expressed intent. Voice search phrases have the clearest intent (‘open,’ ‘turn on,’ ‘find,’ ‘build’) compared to traditional search phrases. People always put a clear intention into voice commands. The intent in voice phrases should be expressed briefly and as concisely as possible.
Long queries. Verbal queries are longer than written ones. For example, ‘Where can I buy cat food in city X?’ A written query will most likely be twice as short: ‘cat food in city X’, ‘buy cat food’. Therefore, you need to add complete phrases to the semantic core, even if they are not high-frequency.
When collecting semantics, you also need to use:
- various abbreviations;
- queries that begin with question words such as ‘who,’ ‘how,’ ‘where,’ ‘what,’ etc.;
- jargon and slang;
- specific expressions and names that people use when communicating with each other.
