Perguntas Frequentes

Common questions about AI voice for e-learning

Most platforms accept AI-narrated courses. Udemy, Skillshare, and Teachable allow AI voices as long as the content is high quality. Some platforms may require disclosure. Check your target platform's current policy on AI-generated content.

GLM-TTS by Tsinghua University achieves the lowest character error rate among open-source TTS models. This means it produces the most accurate pronunciation of words, names, and technical terms — critical for educational content.

Yes. Use CosyVoice 2 or GPT-SoVITS with voice cloning to maintain the same instructor voice across multiple languages. Clone the original instructor voice, translate the script, and generate audio in each target language.

GLM-TTS handles most technical terms well. For unusual acronyms, you can spell them out phonetically in the script (e.g., write "sequel" instead of "SQL" if you want that pronunciation). SSML support is available for fine-grained pronunciation control on some models.

AI-generated audio helps meet ADA, Section 508, and WCAG 2.1 requirements by providing audio alternatives for text content. This supports students with visual impairments, dyslexia, and other reading disabilities. Audio versions of course materials are increasingly required by educational institutions.

A typical 10-hour online course costs approximately $50-500 in credits depending on the model used. Free models (Piper, MeloTTS) cost nothing. Compare this to $20,000-50,000 for professional voice actor narration of the same course.

Yes. Simply edit your script and regenerate the affected audio segments. This is a major advantage over traditional voice recording, where any content change requires booking studio time and re-recording. AI narration makes iterative course updates effortless.

Generate narration per slide or per section, then align each audio clip with its corresponding slide in your video editor or authoring tool. This gives you precise control over timing. Many LMS platforms like Articulate and Captivate support per-slide audio import.

Yes. Choose a warm, clear voice and a slightly slower speaking pace for younger audiences. Bark can add engaging sound effects and expressive elements that keep young learners interested. Many K-12 educational publishers use AI narration for supplementary audio content.

Yes. Integrate the REST API with your learning management system to automatically generate audio when new lessons are published. This enables a fully automated content pipeline where instructors write text and audio is produced on demand.

Generate audio for quiz questions, answer explanations, and feedback prompts separately. Embed them in your interactive courseware at the appropriate trigger points. For real-time quiz feedback, use fast models like Kokoro that respond in under a second.

Yes. Use the API to offer voice selection in your LMS. Generate and cache audio in multiple voices, or generate on demand when a student selects a different voice. This personalization improves learner engagement and accessibility.
