🎤 Speech Recognition (ASR)
Captures spoken language and converts it to text with up to 95% accuracy for clear speech.
🧠 Neural Translation (NMT)
Translates text while maintaining context. Modern models understand linguistic nuances.
🔊 Text-to-Speech (TTS)
Converts translated text back into sound with natural intonation.
Latency: 2-3 seconds
AI Translation Accuracy: 2025 Data
AI translation quality has significantly improved thanks to transformer architectures and deep learning. However, accuracy varies depending on language pair.
| Language Pair | AI Accuracy | Quality | Recommendation |
