Oracle's service for converting speech to text and text to speech. Like having a universal translator between spoken words and written text.

All of these services provide APIs to convert audio to text (speech recognition) and/or generate natural-sounding audio from text (speech synthesis). OCI Speech covers both directions, similar to Azure’s unified Speech service; AWS and GCP commonly use separate products for STT vs TTS.
