Anything They Can Say, We Say it Better

The LumenVox TTS Server provides Text-to-Speech synthesis, turning written text into spoken speech. This technology allows any computer or IVR application to convey information to a user providing an accurate and affordable means of speech enabling your telephony platform or software application.

Some common uses include telephone systems, automotive applications, and programs to assist the disabled. It is particularly useful when reading dynamic data that cannot be pre-recorded, such as reading live text from the Web or a street address from a database.

The LumenVox Text-to-Speech Server can be run on 32 or 64-bit versions Windows or Linux (Red Hat or CentOS), on any machine with a modern (2 GHz or better) processor, with at least 4 CPU cores and 2 to 8 GB of RAM. It is designed to be controlled via our C/C++ API or MRCP versions 1 or 2.

Male & Female Voices Offered:

Feel free to try the LumenVox TTS Server for yourself by using the interface at the top of this page.

*Most of the voices featured on this website are sampled at 22 KHz. This is higher than the sampling rate of most telephone systems (which are limited to 8 KHz), so 8 KHz voices designed for telephony applications or IVRs will have lower fidelity.
