VeriSpeak SDK.

VeriSpeak SDK capabilities.

• Performance and platforms

  Development platforms

  VeriSpeak as a speaker recognition algorithm ensures the system's security by verifying the authenticity of both the voice and the phrase. Voiceprint patterns can be matched in 1-to-1 (verification) and 1-to-many (identification) modes.

  Available as a software development kit that allows you to develop stand-alone and networked solutions on Microsoft Windows, Linux, macOS, iOS, and Android platforms.

• Text-dependent algorithm

  Text-dependent algorithm

  Text-dependent speaker recognition is based on speaking a single phrase for registration and verification. The VeriSpeak algorithm determines whether a voice sample matches a pattern extracted from a particular phrase. During registration, the person registering is asked for one or more phrases. Later, that person may be asked to say a certain phrase for verification. This method protects against the use of this person's secretly recorded random phrase.

• Two-factor authentication using a passphrase

  Two-factor authentication using a passphrase

  VeriSpeak's voiceprint matching algorithm can be configured to work in a scenario where each user records a unique phrase (such as a passphrase or answer to a "secret question" that only the registered person knows). Later, the person is recognized by their specific phrase with high accuracy. The overall security of the system is increased because the authenticity of the voice and the passphrase are verified.

• Text-independent algorithm

  Text-independent algorithm

  Phrase-independent speaker recognition uses different phrases to register and recognize users. This method is more convenient, as it does not require each user to remember a passphrase. It can be combined with a text-based algorithm for faster text-independent searching followed by phrase validation using a more robust text-based algorithm.

• Live voice detection

  Live voice detection

  The system may require each user to register a set of unique phrases. Later, the user will be prompted to say a specific phrase from the registered group. In this way, the system can guarantee the verification of a live person (as opposed to an impostor who uses a voice recording).

• Possibility of identification

  Possibility of identification

  VeriSpeak functions can be used in 1-to-1 (verification) and 1-to-many (identification) mapping modes.
