From Signal to Turn: Interactional Friction in Modular Speech-to-Speech Pipelines

This paper analyzes interactional friction in modular Speech-to-Speech Retrieval-Augmented Generation (S2S-RAG) systems. It identifies three patterns of conversational breakdown: Temporal Misalignment, Expressive Flattening, and Repair Rigidity. The study argues that these are structural consequences of modular design prioritizing control over fluidity, advocating for choreographing seams between components rather than optimizing them in isolation to achieve conversational coherence.

Deep Analysis & Enterprise Applications

Select a topic to dive deeper, then explore the specific findings from the research, rebuilt as interactive, enterprise-focused modules.

Modern speech AI systems often feel conversationally broken due to rigid turn-taking, unnatural pauses, and inability to adapt in real-time. This paper categorizes these into:

  • Temporal Misalignment: System delays violating user expectations of conversational rhythm.
  • Expressive Flattening: Loss of paralinguistic cues leading to literal, inappropriate responses.
  • Repair Rigidity: Architectural gating preventing real-time error correction.

These are not defects, but structural consequences of modular designs prioritizing control over fluidity. Achieving conversational coherence requires choreographing the seams between components.

The modular S2S-RAG pipeline, while offering engineering control, introduces significant interactional friction. This section details the trade-offs at various layers:

  • ASR: Speed vs. Robustness (e.g., Typhoon's speed vs. Google STT's accuracy with jargon).
  • LLM: Latency vs. Reasoning (lightweight models for speed vs. high-fidelity models for complex tasks).
  • Hybrid Solution: Textual Repair Layer to correct ASR errors with minimal latency.

The "unnatural" pauses are an accumulated structural cost of transforming raw signals into context-aware responses.

To overcome interactional friction, future work should focus on:

  • Multi-Party Conversation: Managing complex turn-taking and speaker diarization in group settings.
  • Full-Duplex Interaction: Implementing robust Acoustic Echo Cancellation (AEC) and incremental processing for ASR, LLM, and TTS to allow "barge-in" and real-time re-planning.
  • Proactive Latency Management: Using reasoning delays productively (e.g., "Understood...") and incorporating human-like non-lexical vocalizations.
  • Multimodal Signal Integration: Integrating gaze, head pose, and gestures for richer interactional floor management.

The goal is to skillfully turn a distributed system into a coherent conversational partner by choreographing complex seams.

Case Study: Overcoming 'Repair Rigidity' in Customer Support

A user reported an ASR mis-transcription of "Azure" as nonsense. With a traditional half-duplex system, the user was forced to wait through a 15-second loop of frustration. Our proposed full-duplex incremental processing would allow immediate "barge-in" to correct the error, reducing resolution time and improving user satisfaction significantly.
