Improving Language Learning Outcomes with Real-Time Speech Recognition
A leading digital education provider wanted to enhance its language-learning platform with real-time pronunciation feedback and interactive speech evaluation. Their existing system relied heavily on manual assessments and delayed feedback cycles, slowing learner progress and limiting scalability.
By implementing IBM Watson Speech to Text, integrated and deployed with Nexright’s expertise, the organization built a robust AI-powered pronunciation engine capable of analyzing speech instantly, identifying errors, and generating actionable recommendations for each learner. This significantly improved learning outcomes, user engagement, and the platform’s ability to scale globally.
Business challenge
As user demand grew, the organization struggled with the limitations of its manual and semi-automated speech evaluation process. Teachers could not provide real-time correction to thousands of learners, which resulted in inconsistent user experiences and higher operational burden.
Key Challenges:
- Inability to scale manual pronunciation assessment across thousands of daily active users.
- Delayed feedback cycles, slowing language acquisition and learner confidence.
- Inconsistent scoring accuracy across instructors and sessions.
- Lack of automation, making it difficult to expand into new regions and languages.
- Limited insights into learner performance trends, preventing personalized recommendations
The organization required an AI-driven, real-time speech recognition platform to automate evaluation, improve accuracy, and provide consistent learning experiences.

FAQ's
IBM Watson Speech to Text is a highly accurate AI service that transcribes spoken audio into written text using deep learning and natural language processing (NLP). It works by breaking down audio files into phonetic representations and mapping them to words using advanced acoustic and language models. This makes it ideal for applications like contact center automation, voice-enabled apps, and real-time transcription services.
IBM Watson Speech to Text supports over 30 languages and dialects, including English (US, UK, Australia), Spanish, French, Japanese, Arabic, and Mandarin. It also includes domain-specific models—such as narrowband (for telephony) and broadband (for high-quality audio)—to ensure transcription accuracy based on the audio environment.
Out-of-the-box, Watson STT achieves high word error rate accuracy thanks to its AI training. However, accuracy can be further improved by uploading custom language and acoustic models, defining grammars, and incorporating domain-specific vocabulary. This is particularly useful in industries like legal, healthcare, and finance, where terminology is specialized.
Yes, Watson STT provides low-latency streaming transcription through WebSocket or HTTP interfaces. It is designed for real-time use cases such as live subtitling, voice command recognition, and real-time customer support monitoring. Developers can use IBM’s SDKs and APIs to embed real-time capabilities directly into their applications.
While Google Speech-to-Text and AWS Transcribe offer comparable capabilities, IBM Watson Speech to Text stands out for enterprise readiness, high configurability, hybrid-cloud deployment support, and strong governance options.
