Certified - Intermediate AI Audio Course

This episode introduces the fundamentals of speech and audio AI, covering three main areas: speech-to-text (STT), text-to-speech (TTS), and speaker identification. STT systems convert spoken language into written text, supporting applications like transcription and voice assistants. TTS systems perform the reverse, synthesizing natural-sounding speech from text, enabling accessibility tools and interactive systems. Speaker identification focuses on recognizing or verifying individuals based on voice characteristics. For certification exams, these distinctions are important, since each application relies on different model architectures, training data, and evaluation criteria.

Practical scenarios highlight use cases and challenges. STT models may struggle with background noise or varied accents, requiring robust datasets and noise-handling techniques. TTS systems face challenges in generating natural prosody, often mitigated with deep learning models trained on large, diverse corpora. Speaker ID introduces security considerations, such as spoofing risks, which connect to broader AI safety topics. Exam questions may present cases asking which approach is most relevant for a given business problem, or how to troubleshoot poor accuracy in noisy conditions. Learners benefit from linking each system type to real-world examples and understanding the unique strengths and limitations they present.
