Lingvanex Local Speech Recognition Performance Review
This work was conducted with the aim of comparing the translation performance of different language models for several language pairs, namely English, Spanish, Portuguese, French, German, Arabic.
When evaluating translation quality, we used two key metrics: Word Error Rate (WER) and Character Error Rate (CER). WER measures the number of incorrect words in the translation compared to the source text, expressed as a percentage. The lower the WER, the more accurately the system recognizes speech. CER, on the other hand, evaluates the accuracy of the translations at the character level, also expressed as a percentage. A lower CER indicates that the system recognizes speech more accurately. Both metrics provide insight into the performance of the language models under test.
For English, the tuned_small model achieved a WER of 9% and a CER of 4%, while the large-v3 model had a WER of 58% and a CER of 44.5%. This results in a difference of 49% for WER and 40.5% for CER.
For Spanish, the tuned_small model performed better with a WER of 11% and a CER of 5%, compared to the large-v3's WER of 68% and a CER of 45%, showing differences of 57% and 40%, respectively.
In French, the tuned_small model had a WER of 10% and a CER of 5%, while the large-v3 model scored 60% for WER and 38.5% for CER, resulting in differences of 50% and 22.5%.
For German, the tuned_large model achieved a WER of 28% and a CER of 30%, compared to the large-v3's WER of 57.8% and a CER of 30%, indicating differences of 28% for WER and no difference for CER.
In Arabic, the large-v3 model had a WER of 4% and a CER of 52%, while the tuned_large-v2 model scored 4% for WER and 2.2% for CER, leading to differences of 0% for WER and 49.8% for CER.
Lastly, for Portuguese, the tuned_large-v2 model achieved a WER of 10% and a CER of 35.3%, while the large-v3 had a WER of 51.86% and a CER of 26%, resulting in differences of 41.86% for WER and 9.3% for CER.
Overall, the analysis showed varying levels of performance across the different models and languages tested, with the tuned_small and large-v3 models showing noticeable differences in WER and CER. This suggests that tuning the model significantly improved the performance, which ultimately resulted in high-quality speech recognition for such rare languages.
Below are tables summarizing the Word Error Rate (WER) and Character Error Rate (CER) for six languages (Spanish, Portuguese, French, German, Arabic and Hindi). The difference column shows the performance difference between the large-v3 model and the corresponding tuned model.
Table 1: Word Error Rate (WER%)
| Language | Tuned Model | WER (%) Tuned | WER (%) Large-v3 | Difference |
|---|---|---|---|---|
| English | tuned_small | 9 | 58 | 49 |
