Translate Spanish to English Audio With AI Agents

Smartcat's AI agents support audio and text translation across 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.

Smartcat’s Media Translation Agent achieves 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.

Smartcat’s Media Translation Agent transcribes the Spanish audio with advanced automatic speech recognition (ASR), then translates the content to English. You can activate Smartcat's AI-powered voice dubbing to generate English audio that mirrors the pacing and inflection of the original audio.

Smartcat's Media Translation Agent automatically generates subtitles 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.

Most standard audio files are fully transcribed and translated in under 5 minutes with the Media Translation Agent. This represents up to a 400% improvement in speed compared to traditional agency workflows. Even high-volume batches can be processed concurrently, which helps global teams meet tight deadlines without sacrificing accuracy.

The collaborative Smartcat Editor allows you to fine-tune any translations. Any changes you make are stored in your translation memory, improving quality and reducing rework in future projects.

Smartcat's Media Translation Agent can extract Spanish audio directly from video files (e.g., MP4, MOV), then can transcribe, translate, generate subtitles, and dubb the content into English— all within a single platform. This is ideal for marketing videos, eLearning courses, or internal communications that need localization at scale.

Smartcat’s enterprise-grade security includes encryption at rest and in transit, GDPR and SOC 2 compliance, and private workspaces. Your content is never used to train external models, ensuring full confidentiality from upload to download.
