Description

Inworld Realtime STT is a streaming API for speech-to-text that captures more than just spoken words. This innovative tool merges low-latency speech recognition with voice profiling capabilities, allowing it to analyze emotions, vocal style, accent, age, and pitch from raw audio inputs, which enhances the responsiveness and expressiveness of downstream LLMs and TTS systems. Developers have the flexibility to stream audio in real time, transcribe entire files, or gather voice profile signals via a single, comprehensive API. The system features real-time bidirectional streaming over WebSocket, synchronous transcription for complete audio files, and offers voice profile signals for each streaming segment, all while supporting multiple providers through one model ID. Each audio segment provides a dynamic profile of the speaker, complete with confidence scores, equipping LLMs with structured context that indicates the emotional state of the user, such as whether they sound sad, frustrated, soft-spoken, high-pitched, or calm. This capability allows for a more nuanced interaction, enriching the user experience by adapting responses to the speaker’s emotional tone and vocal characteristics.

Description

Inworld TTS stands out as a cutting-edge text-to-speech solution that provides exceptionally realistic and context-aware speech synthesis alongside advanced voice-cloning features, all at an incredibly affordable price. Its leading model, TTS-1, is tailored for real-time usage, boasting low-latency streaming capabilities—where the first audio segment is available in about 200 milliseconds—and supports a wide array of languages such as English, Spanish, French, Korean, Chinese, and several others. Developers have the flexibility to utilize instant zero-shot voice cloning, requiring only 5 to 15 seconds of audio input, or opt for more detailed fine-tuned cloning, enabling the addition of voice-tags that convey emotion, style, and non-verbal cues, while also allowing for language switching without losing the unique voice identity. For those seeking even greater expressiveness and multilingual capabilities, the TTS-1-Max model is currently in preview, offering enhanced features. The platform accommodates various access methods, including API and portal options, and can operate in either streaming or batch modes, making it suitable for a diverse range of applications such as interactive voice agents, gaming characters, and bespoke audio branding experiences. With its versatility and advanced technology, Inworld TTS is poised to revolutionize how we interact with synthetic voices.
