Speech Devices SDK
- 3. VisionMicrosoft Speech Services Speech To Text Convert speech to text and back again, and understand its intent Custom Speech to Text Fine-tune speech recognition for anyone, anywhere TTS/Custom Voice Speech recognition and analytics and transcription Speaker Recognition Give your app the ability to know who's talking Translator Speech translation
- 4. The Speech Devices SDK is pre- packaged software fine tuned to specific hardware (dev kits), that makes it easy to integrate with the full range of cloud-based Microsoft Speech services, creating rich user experiences for customers. The Speech Devices SDK allows you to choose your device’s custom “wake word” – the cue that initiates a user interaction. Working with Microsoft Speech services and other APIs, the SDK enables tailored Voice AI experiences.
