API Documentation
Introduction
The LMNT Speech REST API provides facilities for synthesizing emotive, human-like speech audio from text input. There is support for creating custom voices from a user-provided audio input data set. Those voices can then be used for speech synthesis, in addition to those already provided as part of the LMNT system.
If you are interested in accessing other functionality via an API (e.g. alignment data, bulk synthesis) please contact us at feedback@lmnt.com.
