Speech-to-Speech Model

A Speech-to-Speech Model is a speech model that can perform direct audio transformation tasks without text intermediary processing.

• AKA: S2S Model, Direct Speech Model, Audio-to-Audio Model, End-to-End Speech Model.
• Context:
  • It can typically process Audio Input Signals through neural acoustic encoders.
  • It can typically generate Audio Output Signals through neural acoustic decoders.
  • It can typically maintain Prosodic Information including intonation patterns and emotional tones.
  • It can typically preserve Speaker Characteristics through voice embeddings.
  • It can typically enable Real-Time Processing with streaming architectures.
  • It can often support Multi-Speaker Modeling through speaker adaptation mechanisms.
  • It can often facilitate Cross-Lingual Transfer through multilingual representations.
  • It can often implement Emotion Transfer between input emotions and output emotions.
  • It can range from being a Monolingual Speech-to-Speech Model to being a Multilingual Speech-to-Speech Model, depending on its language support.
  • It can range from being a Single-Speaker Model to being a Multi-Speaker Model, depending on its voice diversity.
  • It can range from being a Low-Fidelity Model to being a High-Fidelity Model, depending on its audio quality.
  • It can range from being a Emotion-Agnostic Model to being an Emotion-Aware Model, depending on its emotional modeling capability.
  • ...
• Example(s):
  • Commercial Speech-to-Speech Models, such as:
    • GPT-Realtime Speech-to-Speech Model by OpenAI.
    • Translatotron Model by Google Research.
    • Direct S2S Translation Model for simultaneous interpretation tasks.
  • Research Speech-to-Speech Models, such as:
    • Neural Transducer Model for low-latency translation.
    • Transformer-Based S2S Model for attention-based processing.
  • Application-Specific Models, such as:
    • Voice Conversion Model for speaker identity transformation.
    • Speech Enhancement Model for audio quality improvement.
  • ...
• Counter-Example(s):
  • Cascaded Speech System, which uses text intermediate representation.
  • Text-to-Speech Model, which requires text input.
  • Speech Recognition Model, which produces text output.
