Translate Spanish to English audio with AI

Smartcat supports audio and text translation across more than 280 languages, making it one of the most versatile platforms on the market. In addition to Spanish and English, some of the most requested languages include French, Italian, Portuguese, German, Russian, Polish, Hindi, and Chinese. Whether you need to subtitle a marketing video in French, dub training content into Hindi, or translate legal recordings from German to English, Smartcat AI Agents are equipped to handle it with high accuracy and linguistic fluency. The platform dynamically adjusts tone and structure for each language pair, ensuring localized resonance and brand consistency at global scale.

Smartcat’s AI Agents achieve over 95% accuracy in Spanish-to-English audio translation by combining state-of-the-art speech recognition with contextual, neural translation models. This ensures not only word-for-word accuracy, but also retention of tone, nuance, and intent. The system is constantly learning and improving through feedback loops. Whether from human reviewers or your in-platform edits, AI agents continue to learn and improve over time.

Smartcat supports a broad spectrum of audio and subtitle formats, including MP3, WAV, MP4, MOV, SRT, and VTT. This allows you to easily translate everything from recorded interviews and podcasts to full-length video content. AI Agents are designed to seamlessly handle different codecs, bitrates, and transcription complexities without format-specific tuning on your part.

Smartcat’s voice translator operates through an integrated pipeline: Spanish audio is transcribed using advanced automatic speech recognition (ASR), then translated to English using Smartcat AI agents. Optionally, you can activate Smartcat's AI-powered voice dubbing to generate English audio that mirrors the pacing and inflection of the original. Human reviewers can step in at any phase to further ensure cultural, technical, or industry-specific fidelity.

Smartcat AI Agents automatically generate subtitle files that are time-synced and formatted in widely used formats like SRT or VTT. These subtitles are built using context-aware segmentation, which ensures that line breaks align with natural speech pauses—resulting in highly readable and professional subtitles for training videos, social media content, and more.

Thanks to Smartcat’s real-time AI pipeline, most standard audio files are fully transcribed and translated in under 5 minutes. This represents up to a 400% improvement in speed compared to traditional agency workflows. Even high-volume batches can be processed concurrently, letting global teams meet tight deadlines without sacrificing accuracy.

Use Smartcat’s collaborative subtitle and translation editor to fine-tune translations. Any changes you make are stored in your translation memory, improving quality and reducing rework in future projects.
