Today, we're releasing Octave: the first LLM built for text-to-speech. Now you can design any voice with a prompt, give acting instructions to control emotion and delivery (sarcasm, whispering, etc.), and produce long-form content on our Creator Studio. Unlike traditional TTS that just “reads” words aloud, Octave understands how meaning affects delivery to generate emotional, human-like speech. Key features: 🎨 Voice Design: Create any AI voice you can imagine with a simple prompt. From "ASMR Southern meditation coach" to "film noir detective" — Octave instantly generates the voices you need for your content. 🎬 Acting Instructions: Octave is the first TTS system that can take natural language instructions to change emotional delivery and speaking style. 🤔 Context-Aware Expression: Trained on 1000x more language than traditional TTS, Octave understands your script like a human actor, delivering realistic emotions, sarcasm, pace, word emphasis, and more. Octave’s first-of-its-kind voice intelligence speaks for itself 😉 In a blind study, Octave outperformed ElevenLabs Voice Design: 🔊71.6% preferred Octave's audio quality 🗣️51.7% found Octave more natural 🎯57.7% said Octave better matched voice descriptions And the best part? Even with superior capabilities, Octave is cheaper than alternatives.

What effect do emotionally intelligent assistants have on consumer shopping experiences? 🤖 🛍️ Read on to hear insights from a new study between The University of Zurich and Hume AI! Traditional AI voice assistants, like Alexa or Google Assistant, excel at functional tasks (e.g., setting reminders or finding information) but often lack the emotional depth needed for meaningful user connections, especially in emotionally driven settings like shopping for experiential products (e.g., scented candles) or customer service interactions. Researchers at the University of Zurich deployed Hume's Empathic Voice Interface (EVI) in an application to test how shoppers would change their consumer behavior while chatting with an emotionally intelligent AI who could talk them through their decisions. The results showed that users strongly preferred an empathic AI over "utility" focused ones for both experiential and functional purchases. Shoutout to University of Zurich researchers Alex Mari, PhD and Ertugrul Uysal, and our very own Jeff Brooks. Read more below! https://lnkd.in/e9iARq6X
