Introducing dialectal Speech-to-Text models for Arabic

Felix Laumann

Today, we're launching four new Arabic dialectal speech-to-text (STT) models on VoiceAI, the leading platform for audio transcription, analytics, and AI voice generation. Trained on over 40,000 hours of speech data, VoiceAI offers 91% average accuracy in local languages - helping to make AI-enabled services accessible for all. 

This update reflects our commitment to continually advancing technology for regional languages and dialects. More importantly, it paves the way for deeper understanding and connection in sectors where clear and nuanced communication with dialectal words and phrases is essential, such as call centers and customer service.

Diversity of dialects in the Arabic language

The Arabic language, with over 25 dialects, presents unique challenges for speech recognition technologies. The limited availability of training data and the linguistic complexity have resulted in these dialects being overlooked and underserved. However, as the demand for more inclusive and diverse AI tools grows, there's an emerging opportunity for innovation in this space.
From the formal Modern Standard Arabic (MSA) used in official documents and media to the local dialects like Egyptian, Gulf, and Levantine spoken across the Middle East and Northern Africa, fully grasping the intricacies of each Arabic dialect is essential. The stark differences between MSA and these regional dialects underscore the need for speech-to-text technologies to evolve and accurately capture linguistic nuances, catering to a more diverse user base.

VoiceAI’s Dialectal Support

VoiceAI's latest update introduces advanced dialectal STT models, a leap forward in accommodating the linguistic diversity of the Arabic-speaking world. This initiative is not just a technical enhancement but a strategic move to bridge communication gaps, ensuring that VoiceAI remains the most comprehensive and user-friendly audio transcription and analytics platform in the market. By supporting a wider range of Arabic dialects, VoiceAI improves how businesses communicate with their Arabic-speaking customers, ensuring clarity, accuracy, and a deeper cultural connection. 

VoiceAI’s now supports 16 languages including these Arabic dialects:

  • Modern Standard Arabic (MSA) 
  • Gulf Arabic 
  • Egyptian Arabic 
  • Levantine Arabic 


Agent Performance Analysis: Utilize audio analysis to evaluate and improve agent performance, identifying key behaviors that lead to successful customer interactions. This can include tone of voice, clarity of communication, and adherence to protocols.

Actionable Insights: Extract valuable insights from call transcripts to identify common customer issues and optimize call handling processes. This can lead to faster resolution of customer queries and improved customer sentiment.

Call Summarization: Automatically generate concise summaries of customer calls, capturing essential points and action items. This enables quick review and follow-up, ensuring no critical information is missed.

Understanding Customer Sentiment: Analyze the emotional tone and sentiment expressed by customers during calls to better understand their satisfaction levels and concerns. This can help tailor services to meet customer needs more effectively and enhance overall customer experience.

Extract the information you want: By utilizing VoiceAI’s Ask Me Anything feature, users can analyze call transcripts for any key information that would take a long time to manually find. For example, Ask Me Anything allows to detect promises of agents during calls with customers and summarizes them at the end, so the agent has a clear to-do list after each call.

Impact of Dialectal Models

The introduction of new dialectal models in VoiceAI has significant implications, especially in enhancing communication and transcription accuracy. Let's explore some examples of how switching to dialectal models can make a difference:

Navigation Systems: Many store and street names use dialectal words in Arabic, and they are important to transcribe accurately when using voice features on navigation apps like Google Maps. Misidentifications of store and street names impact their users’ safety because they can’t use their voice features and need to type these names while driving. VoiceAI's models are fine-tuned for these nuances, ensuring accurate, easy-to-find store and street names.

Sentiment Analysis: Emotionally charged words and phrases are often missed or misinterpreted by models trained on Modern Standard Arabic because they only in dialects, skewing sentiment analysis. VoiceAI's dialectal models improve emotion detection, offering businesses deeper insights into customer feelings, crucial for enhancing satisfaction and services.

Captioning: Dialectal Arabic is vital for accurately captioning dialogues in movies and TV shows. Characters often speak in regional dialects, posing a challenge for standard transcription models. VoiceAI's dialectal models excel in capturing these nuances, ensuring precise captions that enhance the viewing experience. 

For professionals in the call center and conversational experience industry, this development offers a unique opportunity to enhance their operations and connect more meaningfully with their customers. Reach out to the VoiceAI team today to see how these capabilities can be integrated into your business. 

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
