Unbabel - Key Features and Functionality
Unbabel’s Speech Tools
Unbabel’s AI-driven products offer several key features that facilitate multilingual communication with high accuracy and efficiency. Here are the main features and how they work:
Automatic Speech Recognition (ASR)
Unbabel’s speech tools utilize ASR to transcribe spoken messages into text. This process involves the user speaking a message, which the system recognizes and converts into a written transcript. If there are errors in the transcription, the user can edit the text manually.
Translation Pipeline
The transcribed text is then sent through Unbabel’s translation pipeline, which combines machine translation with human verification. This ensures high-quality translations, either through Unbabel’s quality estimation (QE) tool or with the help of a global community of translators.
Text-to-Speech (TTS)
After translation, the text can be converted back into audio using TTS models. The current version of Unbabel Talk synthesizes audio using standard male or female voices, while forthcoming versions are set to include features like voice morphing, allowing the synthesized text to be delivered in the user’s own voice.
Human-Verified Translations
Unbabel ensures the quality of translations by either using its QE tool or involving its community of translators. This human touch helps maintain the authenticity and accuracy of the translations, which is crucial for effective communication across different languages.
Integration with Messaging Platforms
Unbabel Talk allows users to send translated voice messages through popular messaging platforms such as WhatsApp, Facebook Messenger, and others. This integration enables seamless multilingual communication without the need to switch between different apps.
Voice Morphing and Transcription Correction
In the forthcoming versions of Unbabel Talk, features such as voice morphing and transcription correction by translators are being developed. Voice morphing will allow the synthesized text to be delivered in the user’s own voice, and transcription correction will eliminate the need for users to manually edit transcription errors.
AI Integration
Unbabel’s products are powered by AI, which drives the ASR, TTS, and translation processes. The AI technology is refined by a global community of translators, ensuring that the translations are not only fast and scalable but also accurate and authentic. This combination of machine translation and human oversight ensures high-quality multilingual support.
Seamless Workflow Integration
Unbabel integrates seamlessly with various customer service platforms, such as Intercom, Salesforce, and others. This integration allows customer support agents to communicate with customers in their native languages without disrupting their existing workflows. Agents can respond to international customers in real-time, enhancing the customer experience and improving metrics like NPS, CSAT, and CES.
By combining these features, Unbabel provides a comprehensive solution for multilingual communication, making it easier for businesses to serve customers globally while maintaining high standards of quality and customer satisfaction.

Unbabel - Performance and Accuracy
Performance
Unbabel’s latest advancement, TowerLLM, has demonstrated superior performance in machine translation. This model, built on large public models and trained on high-quality data, outperforms competitive models from companies like Google, DeepL, and even other generative AI models like GPT-4.
TowerLLM shows substantial improvements in translation quality, particularly in capturing the nuances of language and producing natural and fluent translations. This results in reduced need for manual post-editing and review, simplifying the translation process and enabling faster time-to-market for multilingual content.
Accuracy
The accuracy of Unbabel’s translations is significantly enhanced by its Quality Estimation (QE) technology. This system identifies incorrect words in translated sentences and provides an automatic quality score, guiding human post-editors to focus on the parts that need correction. Unbabel’s QE system has won competitions with a high F1 score, indicating its effectiveness in evaluating translation quality.
Unbabel also uses COMET, a framework for evaluating machine translation models, which correlates well with human scores of quality. This ensures that the automated metrics effectively highlight critical errors and maintain high translation accuracy.
Real-Time Quality Reporting
Unbabel has introduced real-time, AI-powered Quality Reports, which provide complete visibility into translation quality. These reports automate the quality evaluation process, eliminating the need for time-consuming and expensive manual reviews. This feature allows businesses to make prompt, data-driven decisions and proactively address potential quality issues.
Limitations and Areas for Improvement
Despite the advancements, there are some limitations and areas where Unbabel can improve:
- Response Times and Reliability: Some users have reported unpredictable response times and occasional delays in receiving translations, which can be frustrating for teams relying on quick turnaround times.
- Human Intervention: While Unbabel’s AI is highly advanced, it still cannot fully replace human intervention, especially in complex translations. Some translations may still require tweaking, and certain contexts or domains may not be fully captured by the AI models.
- Integration Issues: There have been reports of poor integration with certain platforms, such as Zendesk Guide, which lacked simple features like bulk article selection and accurate translation statuses.
- Non-Text Content: Unbabel currently does not support the translation of pictures or other non-text content included in messages, which can be a significant limitation for some users.
Overall, Unbabel’s performance and accuracy are highly regarded, thanks to its advanced AI models and quality estimation technologies. However, there are areas where improvements can be made to enhance user experience and address specific limitations.
