VeriSpeak SDK System Requirements

• PC or Mac with x86 (32-bit) or x86-64 (64-bit) compatible processors. 2GHz or better processor is recommended.
• At least 128 MB of free RAM should be available for the application. Additional RAM is required for applications that perform 1-to-many identification, as all biometric templates need to be stored in RAM for matching. For example, 1,000 templates (each containing 1 voice record) require about 5 MB of additional RAM.
• Free space on hard disk drive (HDD):
  • at least 1 GB required for the development.
  • 100 MB required for VeriSpeak components deployment.
  • Additional space would be required in these cases:
    • VeriSpeak does not require the original voice sample to be stored for the matching; only the templates need to be stored. However, storing voice samples on hard drive for the potential future usage is recommended.
    • Usually a database engine runs on a separate computer (back-end server). However, DB engine can be installed on the same computer for standalone applications. In this case HDD space for templates storage must be available. For example, 10,000 templates (each containing 1 voice record extracted from 5-seconds long sample) stored using a relational database would require about 50 MB of free HDD space. Also, the database engine itself requires HDD space for running. Please refer to HDD space requirements from the database engine providers.
• Microphone. Any microphone that is supported by the operating system can be used.
• Database engine or connection with it. VeriSpeak templates can be saved into any DB (including files) supporting binary data saving. VeriSpeak Extended SDK contains the following support modules for Matching Server:
  • Microsoft SQL Server (only for Microsoft Windows platform);
  • PostgreSQL (for Microsoft Windows and Linux platform);
  • MySQL (for Microsoft Windows and Linux platforms);
  • Oracle (for Microsoft Windows and Linux platforms);
  • SQLite (for all platforms).
• Network/LAN connection (TCP/IP) for client/server applications. Also, network connection is required for using Matching server component (included in VeriSpeak Extended SDK). Communication with Matching server is not encrypted therefore, if communication must be secured, a dedicated network (not accessible outside the system) or a secured network (such as VPN; VPN must be configured using operating system or third party tools) is recommended.
• Microsoft Windows specific requirements:
  • Microsoft Windows XP / Vista / 7, 32-bit or 64-bit.
  • Microsoft .NET framework 2.0 or newer (for .NET components usage).
  • One of following development environments for application development:
    • Microsoft Visual Studio 2005 SP1 or newer (for application development under C/C++, C#, Visual Basic .Net)
    • Sun Java 1.5 SDK or later
• Linux specific requirements:
  • Linux 2.6 or newer kernel, 32-bit or 64-bit.
  • glibc 2.7 or newer
  • GStreamer 0.10.23 (with gst-plugin-base and gst-plugin-good) or newer (for voice capture using microphone)
  • libasound 1.0.x or newer (for voice capture)
  • udev-143 or newer with libudev (for microphone usage)
  • GTK+ 2.10.x or newer libs and dev packages (to run SDK samples and applications based on them)
  • GCC-4.0.x or newer (for application development)
  • GNU Make 3.81 or newer (for application development)
  • Sun Java 1.5 SDK or later (for application development with Java)
  • pkg-config-0.21 or newer (optional; only for Matching Server database support modules compilation)
• Mac OS X specific requirements:
  • Mac OS X (version 10.4 or newer)
  • XCode 2.4 or newer (for application development)
