Speech verification is a feature of speech recognition software that verifies specific patterns of speech, including cadence, pitch, and tonal variations. It can be used for language coaching or security purposes by comparing speech patterns to archived recordings.
Speech verification is an aspect of speech recognition software that uses a computer program to anticipate certain specific patterns of speech and then verify that those patterns are found in a voice recording or in a live person speaking. These patterns are typically related to the cadence, pitch, and tonal variations common to a person speaking. This feature in speech recognition software can be used to help train a person on how to speak correctly with a certain accent or vocal inflection, which is beneficial to someone trying to learn a particular style of speech. Speech verification can also be used with speech recognition programs to verify that a specific speaker is speaking and this is often used for security applications.
In general, speech verification is a process by which a computer program is able to not only recognize but also verify certain aspects of spoken audio. This typically uses other recorded speech sources to compare and find differences and similarities. Such verification usually uses certain aspects of speech such as pronunciation, tone of voice, and syllabic stresses placed on certain words while speaking. Speech verification software is often used to recognize general patterns in a certain type of speech or unique ways a specific person speaks.
General types of speech verification are often used in coaching or teaching a person to speak a new language or to learn a specific dialect or accent of a language. This can often be used by actors, politicians and diplomats to develop speech patterns that more closely fit a linguistic ideal. Computer programs with this type of speech verification will usually analyze a user’s speech and compare it to accepted speech samples using the desired accent. The changes the user would need to make will be explained, and most programs will provide audio clips for users to hear the differences as well.
Voice verification can also be used for security purposes in connection with speech recognition software. This type of software will be programmed with audio samples from a specific person speaking, which are then analyzed to isolate certain speech patterns indicative of that speaker. The recordings are then archived and can be compared to future speeches to verify the speaker’s identity. With this type of voice verification program, a bank or similar company can allow customers to log into personal accounts over the phone and ensure that the customer is calling by analyzing the customer’s voice. Such programs are not necessarily inexpensive or widely used, but for some applications they can be very useful.
