The Google Speech-to-Text API is a cloud-based service that converts audio into text using Google’s advanced machine learning models. It allows developers to build voice-enabled features into apps, especially where real-time transcription is needed.

In travel apps, it is used to transcribe user voice input like:

“Book a 5-star hotel in Bangkok with a pool and breakfast.”

Once transcribed, the text is passed on to an NLP engine to complete the task. The Speech-to-Text API can process hundreds of languages, making it ideal for global or multilingual travel platforms.

Why Travel Companies Use Google Speech API:

• High accuracy in voice transcription, even with accents
• Real-time streaming and response capabilities
• Optimized for noisy environments like airports or streets
• Supports punctuation, timestamps, and audio formatting

Common Use Cases:

• Voice-based search and booking
• Voice navigation in mobile apps
• In-destination queries via wearable or smart speaker
