VeriSpeak SDK

Speaker recognition for stand-alone or Web applications

VeriSpeak voice identification technology is designed for biometric system developers and integrators. The text-dependent speaker recognition algorithm assures system security by checking both voice and phrase authenticity. Voiceprint templates can be matched in 1-to-1 (verification) and 1-to-many (identification) modes.

VeriSpeak is available as a software development kit that enables the development of stand-alone and Web-based applications on Microsoft Windows, Linux, Mac OS X and Android platforms.

Advantages of VeriSpeak

  • Text-dependent algorithm prevents unauthorized access with a covertly-recorded user voice.
  • Two-factor authentication by checking voice biometrics and pass-phrase authenticity.
  • Regular microphones and smartphones are suitable for recording user voices.
  • Available as a multiplatform SDK that supports multiple programming languages.
  • Reasonable prices, flexible licensing and free customer support.

Technology and SDK

  • VeriSpeak algorithm features and capabilities. The VeriSpeak offers text-dependent and text-independent speaker recognition and capable of performing voiceprint verification and identification. Multiple samples of the same phrase and fused matching can be used to improve recognition quality. Read more
  • VeriSpeak 3.0 Standard and Extended SDK. The VeriSpeak Standard SDK is designed for stand-alone PC-based, embedded or mobile biometric application development and the Extended SDK is suitable for developing Web-based biometric systems. Both SDKs include Voice Matcher and Extractor components; the Extended SDK also includes the Voice Client component. Read more
  • Recommendations and constraints for speaker recognition. VeriSpeak has certain requirements for microphone settings and position, as well as user behavior and environment. A passphrase should be kept secret and not spoken in an environment where others may hear it. Read more
  • System requirements. VeriSpeak-based software can be run on PCs or mobile/embedded devices. Windows (for x86 and x86-64), Linux (for x86 and x86-64), Mac OS X (for x86 and x86-64) and Android (for ARM-based processors) platforms are supported. A regular microphone or smartphone is suitable for voice capture. Read more
  • Technical specifications. VeriSpeak extracts a template in 0.6 seconds and can match up to 8,000 voiceprints per second on a PC. A single voiceprint template requires about 4 kilobytes, when 5-second voice samples are used. Read more
  • Reliability tests. The VeriSpeak template extraction and matching algorithm has been tested with the voice samples XM2VTS database and Neurotechnology's internal databases. Read more
  • Download. A VeriSpeak brochure and VeriSpeak 30-day SDK Trial are available for downloading.

Licensing, prices and ordering

  • Licensing options. To develop a VeriSpeak-based product, an integrator should obtain either the Standard or Extended SDK. A license for a VeriSpeak component is required for each computer or device that run this component. Single computer licenses and enterprise licenses are available. Read more
  • Pricing. VeriSpeak Standard SDK costs € 339, the Extended SDK costs € 859. Prices for additional component installation licenses depend on type and quantity. Read more.
