Yandex SpeechKit is Yandex Cloud's speech technology platform offering text-to-speech (TTS) synthesis and speech-to-text (STT) recognition for Russian and other languages.
With the Yandex SpeechKit integration in AACFlow, you can:
- Text-to-Speech (Synthesize): Convert text to audio in various voices and formats
- Speech-to-Text (Recognize Short): Transcribe short audio files (under 1 minute) to text
This integration enables automated voice response systems, audio content generation, and speech-driven workflow triggers.
Usage Instructions
Integrate Yandex SpeechKit into the workflow to add voice synthesis or audio transcription. Requires a Yandex Cloud IAM token. Obtain IAM tokens using the Yandex Cloud IAM block in your workflow.
