What Is a Speech-to-Text?

Technology that automatically converts spoken audio into written text, enabling computers to process and understand what a person has said.

Definition

Speech-to-text (STT), also called automatic speech recognition (ASR), is the technology that transcribes spoken language into written text in real time. Modern STT systems use deep learning models trained on massive amounts of speech data to achieve high accuracy across different accents, speaking speeds, and audio conditions. In business applications, STT is the first step in processing a phone call: the caller speaks, the audio is transcribed, and then NLP processes the text to understand the meaning. Accuracy and latency are the key performance metrics for STT in voice AI applications, as errors in transcription cascade into misunderstandings.

Why It Matters for Service Businesses

The quality of speech-to-text directly affects how well an AI receptionist performs. Poor transcription leads to misunderstood requests, missed details, and caller frustration. For home service businesses where accurate job information (address, problem description, urgency) is critical, high-accuracy STT is non-negotiable.
