AI speaking practice works.
The doubt is over. Randomized trials from Harvard, international meta-analyses, and 150+ peer-reviewed studies all land in the same place — and the case starts the moment you scroll.
2.1× better outcomes at 60–80% lower cost than traditional methods, with zero speaking anxiety.

University research: AI vs. the classroom.
Randomized controlled trials from leading institutions show AI tutoring producing superior outcomes in measurably less time.
AI tutoring produces 2.1× learning gains
194 undergraduates in a randomized controlled trial. AI group median score 4.5 against the classroom's 3.5. Published in Scientific Reports, 2025.
Faster, self-paced completion
70% of AI students finished inside an hour, with no link between time-on-task and score.
Effects hold across the field

The cost reality.
Reaching conversational fluency (B2) takes roughly 600–750 hours of quality practice. How you buy those hours decides the total.
Annual learning cost, by method
Adjust hours per week to see real costs across every path.
Sources: 2024–2025 market rates — private 1-on-1 tutors ($15–25/hr), group classes ($10–20/hr), budget AI ($7–12/mo unlimited). Project Fluency annual range reflects its Tourist and Local plans ($99–360/yr, billed annually or monthly).
How long does it actually take?
Same target — B2 conversational fluency — wildly different timelines, driven by how efficiently each method delivers practice.
The compression effect
Same total hours, but compressed schedules minimize forgetting between sessions — accelerating effective progress by 2–4×.
Sources: Timeline estimates from FSI data (600–750 hours to B2) adjusted for real-world conditions. AI platforms enable higher weekly volume through 24/7 availability and immediate feedback.
Breaking the speaking barrier.
Fear of speaking is the single biggest obstacle to fluency. AI removes it completely.
Study after study documents sharp drops in speaking anxiety, higher willingness to communicate, and stronger motivation when learners practice with AI versus humans — especially early on.
No judgment or embarrassment when you make mistakes
Practice at your own pace, never feeling rushed
Unlimited repetition without social pressure
Build confidence before real conversations

What AI excels at — and what needs humans.
The research is unequivocal: AI excels at specific skills but can't replace human conversation for full communicative competence.
AI excels at
Grammar & syntax
Pattern recognition, conjugations, sentence structure
Vocabulary building
Word exposure, contextual usage, thematic sets
Pronunciation practice
Accent training, phoneme accuracy, instant feedback
Speaking confidence
Zero-judgment practice, anxiety reduction, unlimited reps
Cost-effective practice
60–80% cheaper than traditional study, any hour
Needs real humans
Pragmatic competence
Knowing when to use formal vs. informal by context
Social distance & power
Hierarchy, respect levels, appropriate intimacy
Cultural nuance
Implicit meaning, regional custom, unspoken rules
Natural turn-taking
Interruptions, overlap, real conversational flow
Authentic rapport
Genuine relationships, emotional connection, trust
"Pragmatics is where language intersects with mind, context, and culture — and it is precisely here that LLMs fall short. They do not understand why language is used."
— Laghari (2025), Analysis of AI Language LimitationsSources: Limitations documented in Godwin-Jones (2024) "Generative AI, Pragmatics, and Authenticity in Second Language Learning"; Laghari (2025); U.S. Department of Education (2024) "AI and the Future of Teaching and Learning."
The optimal model: AI training plus human conversation.
The evidence backs hybrid approaches — AI handles practice, instant feedback, and pacing; humans bring pragmatics, culture, and emotional support.
AI training
Grammar, vocabulary, pronunciation, and confidence through unlimited safe practice.
Build foundation
Reach conversational level faster and cheaper than traditional methods alone.
Real teachers, shared memory
Human classes that pick up exactly where your AI practice left off — no re-explaining, ever.
"AI-assisted activities are most effective when complemented by human-led work. The dual-teacher model positions teachers to set the learning design and oversee the AI."
— Human-Centric AI-First Framework, AACSB (2025)
We're your training facility. Not the race.
Project Fluency's AI characters give you unlimited daily speaking practice — no scheduling, no cost barrier, no social anxiety. Then a real teacher takes it from there, picking up from the same shared memory. The AI carries the reps; a human carries the relationship — one continuous conversation, not two separate tools.
