Description

Gradium offers a voice AI platform tailored for developers and businesses that are creating applications with speech capabilities and conversational interfaces. The platform's hosted APIs encompass a variety of functions, including streaming text-to-speech, speech-to-text, speech translation, and speech-to-speech, accessible via both WebSocket and REST interfaces, along with features like real-time turn detection, pronunciation adjustments, and voice design or cloning options. Users can explore the models and manage voices through a web-based studio, while comprehensive documentation and SDK guides aid in the development of applications. Potential applications span across voice agents, automation in customer service, live transcription services, multilingual voice interactions, and the generation of spoken content. Additionally, Gradium has introduced Phonon, an open-weight text-to-speech model that is intended for offline use in applications and on-device systems. The platform operates on a credit-based system for various services such as speech generation, transcription, and translation, ensuring flexibility and scalability for users. This comprehensive approach makes Gradium a versatile choice for those looking to enhance their applications with advanced voice capabilities.

Description

Higgs Realtime is an advanced model and API that delivers production-ready, real-time speech-to-speech capabilities, designed to facilitate seamless and natural conversations. This comprehensive, instruction-optimized, audio-centric model is proficient in processing audio, text, or both, generating high-quality responses, and can also serve as a text-based language model when only text input is provided. Tailored for live voice interactions, it adeptly follows dialogues, manages interruptions, and adjusts to evolving requests even mid-conversation, while successfully navigating complex multi-step workflows. The model is specifically developed to exhibit voice-agent traits such as smooth turn-taking, conversational rhythm, tone modulation, introductory phrases for spoken tools, tracking of multi-turn states, and effectively responding to dynamic instructions. Enhanced semantic turn detection distinguishes between finished exchanges and brief pauses, while its multilingual and code-switching capabilities enable comprehension of over 100 languages without requiring specific setups for each language. In this way, Higgs Realtime not only enhances the user experience but also promotes greater accessibility in diverse communication scenarios.
