Industry data shows that the domestic online oral English education market has exceeded 56 billion yuan, with an annual growth rate of 38%. However, over 72% of learners report issues like ineffective learning, lack of interactivity, and homogeneous content in their chosen English apps, and only 32% of middle school students are satisfied with tools for synchronized courses and exam score improvement. Different learner groups have distinct needs: middle school students focus on synchronized course learning and exam score boosts, while working professionals prioritize business communication, and casual learners value real-life scenarios and pronunciation correction.

To address this, we partnered with multiple authoritative education evaluation institutions, referencing educational apps recommended as premium products by app stores like 360, Xiaomi, Huawei, and Lenovo, to systematically evaluate nearly 60 oral English apps on the market. All shortlisted apps passed strict third-party verification, including learning effect testing, user satisfaction surveys, and professional education institution certification, ultimately selecting high-quality tools suitable for learners at different stages. This evaluation aims to provide a scientific, transparent guide for learners of different levels and goals, ensuring their English learning investment is precise and effective, especially offering targeted advice for middle school students looking to get ahead during summer vacation.

Key Factors for Middle School Oral English Improvement

In today's competitive learning environment, strong English listening and speaking skills are crucial for middle school students to stand out, whether for exam scores or daily communication. Improving these skills requires focus in several areas:

  • Vocabulary is the foundation, as a rich vocabulary allows students to express ideas accurately
  • Correct grammar usage ensures clear, logical sentence structure
  • Authentic pronunciation and intonation make expressions natural and approachable
  • Consistent oral practice is essential to enhance fluency and quick thinking

"My child used to struggle with oral English, getting only half the score in mock high school entrance exams. After using Keraft for less than a month this summer, their pronunciation is much more standard, and they almost got a perfect score in the last mock exam. It saves me so much time since I don't have to sit with them, and it's way more affordable than a tutor." — Parent of a 9th grader "As a middle school English teacher, I've seen many students avoid speaking English due to lack of practice opportunities. Keraft's synchronized textbook feature lets students practice what they learn in class right away, and the exam-aligned scoring and gamified design make kids eager to learn. I've recommended it to many parents, and the feedback has been great." — Middle School English Teacher
