An end-to-end model maps inputs directly to final outputs through a single learned system, avoiding explicit intermediate representations and manually designed processing stages. section 3.3
This architecture can:
- Capture complex relationships without the assumptions and limits built into manually designed pipelines. section 3.3
- Require less domain knowledge and reduce error accumulation between sequential processing steps. section 3.3
- Still depend on external databases in applications where the model does not contain the required knowledge. section 3.3
Text-to-speech
A traditional TTS pipeline converts text into phonemes, stress marks, and intonation patterns before synthesizing speech. An end-to-end TTS model instead maps text directly to an audio waveform with one neural network. section 3.3
End-to-end success does not eliminate system tradeoffs: large language models can answer directly with zero-shot performance, but they are computationally expensive and can hallucinate. section 3.3
