Supported Languages & Dialects

Your AI agent is designed to communicate naturally with customers in multiple languages and adapt its tone to fit your brand’s voice. This section explains which languages are supported, how dialects are handled, and how tone adaptation works.

1. Supported Languages

SymantoAssist supports almost any language for both text (chat) and voice (call) interactions. This enables it to engage with customers around the world in their preferred language.

Commonly Supported Languages

  • Arabic (Modern Standard Arabic, Emirati Arabic, Gulf Arabic, Egyptian Arabic)

  • English (US, UK, Australia)

  • German (Germany, Austria, Switzerland)

  • French (France, Canada)

  • Spanish (Spain, Latin America)

  • Italian

  • Dutch

  • Portuguese (Portugal, Brazil)

  • Polish

  • Swedish

  • Danish

  • Norwegian

  • Finnish

  • Czech

Tip: If your organisation needs additional languages, contact your account administrator or support team to enable them for you.

2. Dialects and Regional Variants

The AI automatically recognises and adapts to regional dialects and language variants.
This ensures that customers experience natural, localised interactions.

Examples:

  • English: Adjusts between American English (“color”) and British English (“colour”).

  • German: Understands both High German and Swiss German phrasing.

  • Spanish: Adapts between Spanish in Spain and Latin American Spanish.

  • Arabic: Can understand and respond in several major dialects, such as Gulf Arabic, Egyptian Arabic, Levantine Arabic, and North African Arabic, while defaulting to Modern Standard Arabic (MSA) for formal or business use.

When configuring your agent, you can specify a default dialect in the language settings.

The AI will then use that variant by default in all its responses.

Tone Adaptation

Tone Adaptation allows your AI to match your organisation’s communication style, whether friendly, professional, or formal.
The AI dynamically adjusts its tone depending on the situation and customer personality traits and sentiment.

Example Tones

  • Friendly / Conversational – Ideal for customer support or sales interactions.

    • Example: “Hey there! How can I help you today?”

  • Professional / Neutral – Suitable for business or corporate environments.

    • Example: “Hello, how may I assist you with your request today?”

  • Formal / Polite – Best for high-sensitivity or regulated industries.

    • Example: “Good afternoon. How may I be of assistance?”

You can define the default tone in your agent’s prompt. The AI will then maintain that tone throughout the conversation.

How Tone Adaptation Works

The AI uses contextual cues and psycholinguistic profiling to choose the most appropriate tone during a conversation.
For example:

  • If the customer sounds upset or frustrated, the AI may respond more empathetically.

  • If the conversation is about an urgent issue, the AI will be more direct and efficient.

  • If the topic is casual, the AI may use a lighter and more engaging tone.

This ensures that every customer interaction feels natural and human-like, regardless of the language or dialect.

Best Practices

  • Choose a default tone that reflects your brand personality.

  • When writing prompts, specify the desired tone explicitly (e.g., “Use a warm and professional tone”).

  • For multilingual agents, define tone expectations per language (some cultures, such as Arabic-speaking regions, prefer a more formal or respectful tone).

  • Periodically test tone output in the Playground to ensure consistency across languages.
