Voice search is a speech recognition technology that allows you to convert a user's voice query into a text form, which is then transmitted to the standard database search system.
The applications most clearly associated with the term "voice search" are based on the use of speech recognition systems and frequent speech synthesis to return search results automatically. Voice search is conducted in the following directions:
- alphabetical directory, search for companies by name or category, search for a person by list;
- search for information such as news, finances, congestion, traffic, weather, or information about movie theaters (this is often used to manage multi-level voice menus);
- search the internet, similar to if the query was typed in the search bar but is done by voice (sometimes results in the text on a mobile phone)
- select options from a long list of services from a mobile service, portable device, or car system (songs or radios).
All of these search forms are initialized with a voice query, the result of which is either the selection of the required action or the delivery of information in the form of synthesized speech. A distinctive feature of these core applications is the quick access to information, minimizing your efforts to locate it.
The reason for using voice is usually because the device you are using is a mobile phone, where text input is inconvenient or dangerously distracting and where it is challenging to view long lists due to the small screen.
Another category of applications that can be considered as part of the voice search - "voice dialing" - search for contacts in the directory. The service is that after a voice calls to the system and determining the required name, it makes a call to the selected contact.
Sometimes, the term "audio search" means searching for audio (or audio recording of a video clip) to find voice fragments and convert them into searchable content. Applications include finding a video or podcast on a specific topic or mentioning a company; Radio companies can convert archived audio/video content into a more user-friendly format, and speakers can find information more easily. This system is based on speech technology to analyze the voice content of files.
When using these technologies in call centers, they are referred to as "speech analyzers", which complements the recognized speech information to perform statistical and linguistic analysis using ready-made text and phonetic materials. Such applications allow you to search for specific audio snippets by the attributes you need (for example, to identify unhappy customer reviews).
For example, converting voice files to text for further text search exists in such services that allow you to convert voice mail into text for easier search and viewing, and also allow for further forwarding of voicemail as e-mail mail or SMS. Services are also available that allow you to leave voice notes on your phone and convert them to text. One of the main goals of this service is to make voice content easy to archive and retrieve.
