SESTEK Text-to-Speech
SESTEK Text-to-Speech converts written text into speech for business applications. It supports more than 20 languages and offers accent-specific voices such as Gulf, Najdi, Kuwaiti, and Emirati Arabic, along with American and British English. Users can adjust tone, pace, emphasis, and volume, and define pronunciations for abbreviations, brand names, product codes, and specialized terms. Common SSML tags cover pauses, pronunciation, external audio, and voice switching. SESTEK can develop a voice model for an organization that is exclusive to it. Deployment is available on-premises or in the cloud, with the same feature set in either arrangement. Standard voices run on Windows, Linux, Docker Compose, and Kubernetes without a GPU; Premium voices require a GPU and run on Linux, Docker Compose, and Kubernetes. APIs and SDKs support integration with existing software. The platform also supports Azure and ElevenLabs integrations and can connect to SESTEK Speech Recognition, Virtual Translator, and AI Agents. Exports include WAV, Opus, MP3, and FLV. Licensing is available through pay-as-you-go, subscription, or custom agreement, but pricing is on request.
