AI Speech Data Collection & Recording for TTS & Speech Recognition Systems

AudioTranscription
Provided high-quality, broadcast-grade US English voice recordings for multiple AI speech training projects. Recorded thousands of scripted lines, conversational scenarios, prompted responses, and emotional variations following strict pronunciation, tone, pacing, clarity, and consistency guidelines. All recordings were captured in a professional home studio (treated acoustic space, broadcast-grade microphone, 24-bit/48kHz WAV files) with excellent signal-to-noise ratio and zero background noise. Delivered clean, isolated audio files with precise file naming and metadata. Contributed directly to improving Text-to-Speech (TTS), voice cloning, and automatic speech recognition (ASR) models. Received consistent positive feedback for natural delivery, reliability, and adherence to complex style guides.
