Higgs Audio / Avatar
Higgs Audio / Avatar is a family of foundation audio and avatar models designed to generate natural speech, understand tone, emotion, and intent, and give voice interactions a visual presence. The models support text-to-speech, speech-to-text, avatar generation, and automatic voice casting that selects an appropriate voice based on context, sentiment, and content. Built for real-world production, Higgs combines expressive generation, robust speech understanding, and flexible deployment for workloads where quality, latency, and reliability matter. High-accuracy multilingual speech recognition supports major languages, while voice cloning reproduces a speaker’s tone from short reference samples to maintain consistent brand voices across interactions. Sentiment detection reads emotional signals in speech to enable smarter routing, stronger analytics, and more context-aware agent behavior.

Orate
Orate is an AI toolkit for speech that enables developers to create realistic, human-like speech and transcribe audio through a unified API compatible with leading AI providers such as OpenAI, ElevenLabs, and AssemblyAI. The platform offers text-to-speech functionality, allowing users to convert text into lifelike speech using a simple API that integrates seamlessly with various providers. For instance, by importing the 'speak' function from Orate and the desired provider, developers can generate speech from text prompts. Additionally, Orate provides speech-to-text capabilities, transforming spoken words into meaningful text with unparalleled accuracy, speed, and reliability. By importing the 'transcribe' function and the chosen provider, users can transcribe audio files into text. The toolkit also supports speech-to-speech transformations, enabling users to change the voice of their audio using a straightforward voice-to-voice API compatible with leading AI providers.

OpenAI Realtime API
The OpenAI Realtime API is a newly introduced API, announced in 2024, that allows developers to create applications that facilitate real-time, low-latency interactions, such as speech-to-speech conversations. This API is designed for use cases like customer support agents, AI voice assistants, and language learning apps. Unlike previous implementations that required multiple models for speech recognition and text-to-speech conversion, the Realtime API handles these processes seamlessly in one call, enabling applications to handle voice interactions much faster and with more natural flow.
