OpenVINO-optimized version of NVIDIA's Parakeet TDT 1.1B V3 model for high-performance multilingual automatic speech recognition on Intel NPUs and CPUs.

## Benchmark Results

**Hardware**: Intel Core Ultra 7 155H (Meteor Lake) with Intel AI Boost NPU
**Software**: OpenVINO 2025.x

### LibriSpeech test-clean (English)

| Metric | Value |
|--------|-------|
| **Average WER** | 3.7% |
| **Median WER** | 0.0% |
| **Average CER** | 1.9% |
| **RTFx (NPU)** | 25.7× |
| **RTFx (CPU)** | 5-8× |
| **Files processed** | 2,620 (5.4 hours) |

### FLEURS Multilingual (24 Languages)

| Metric | Value |
|--------|-------|
| **Average WER** | 17.0% |
| **Average CER** | 5.4% |
| **Average RTFx** | 41.1× |
| **Total samples** | ~15,000+ |

**Best performing languages** (WER): Italian 4.3%, Spanish 5.4%, English 6.1%, German 7.4%, French 7.7%

See [BENCHMARK_RESULTS.md](https://github.com/FluidInference/eddy/blob/main/BENCHMARK_RESULTS.md) for complete per-language results.

## Performance Comparison

| Implementation | Device | RTFx (Avg) | WER (LibriSpeech) |
|----------------|--------|------------|-------------------|
| **eddy (OpenVINO)** | Intel Core Ultra 7 155H NPU | **25.7×** | 3.7% |
| Parakeet (PyTorch) | Intel Arc 140V GPU | ~20×* | ~2.5%* |
| **eddy (OpenVINO)** | Intel Core Ultra 7 155H CPU | **5-8×** | 3.7% |

> **Note**: Benchmarked on HP EliteBook Ultra G1i. eddy NPU is ~1.3× faster than PyTorch on Intel Arc GPU, with lower power consumption. *V3 estimated from V2 benchmark.
