About this app

Ready to actually speak a new language—not just tap through exercises?
SpeakSphere is your AI conversation coach for real-life speaking practice in 8 languages:

English, French, Spanish, Portuguese, Thai, Hindi, German, and Italian.

Choose your native language and the language you want to learn. With 56 native/target combinations, SpeakSphere adapts to you—not the other way around.

Why SpeakSphere?

100% Oral Practice
You learn by speaking, not by memorizing isolated sentences. The AI generates natural back-and-forth conversations for you to repeat aloud every turn.

Smart Repetition in Context
Key sentences and patterns come back with small variations—new words, new structures, same meaning—so vocabulary and grammar stick naturally, in real context.

Fast-Track to Fluency
With regular practice, around 150 hours of guided speaking can unlock a solid intermediate level. Speak confidently in months instead of years of traditional study.

56 Native / Target Language Pairs
Your native language can also be your support language.

Start a guided conversation scenario (travel, daily life, work, small talk, etc.).

Listen, then repeat each sentence aloud.

The AI subtly reshapes key phrases over time, so you absorb structures without needing grammar charts.

Just like a child learning their first language, you activate the brain areas responsible for spoken language. You don’t “translate in your head”—you start thinking in your new language.

Powered by a Fine-Tuned LLM

Thanks to a finely tuned Llama-based model, SpeakSphere generates ultra-natural conversations in real time for your chosen language pair.

Each sentence is designed to:

Reuse important vocabulary at the right moments

Reintroduce key grammar patterns without explicit rules

Feel like real-life speech, not textbook examples

This approach—made possible by Meta’s open-source Llama models, for which we are deeply grateful—lets us offer a flexible, private learning experience that can evolve with modern expressions and everyday language.

Vary Your Scenarios

From ordering coffee or booking a hotel to talking about your weekend, work, hobbies, or travel plans, SpeakSphere adapts to you.

Turn every listening moment into a speaking opportunity.

What’s new

SpeakSphere AI helps you quickly learn many new words through guided repetition directly by speaking. You listen, repeat, reuse words in simple sentences, and review them over time. A forgetting algorithm inspired by human memory highlights words that are starting to fade, so you can review them at the right time. Varied themes help you build vocabulary and speaking reflexes.
