Writing Prompts in Non-English Languages (Using Native Scripts)

Bolna Voice AI agents have multilingual support and can have conversations in serveral languages (see list of all support languages). To ensure natural speech output, it is important to write your prompts in the native script of the target language, rather than phonetically using the English alphabet.

​

Important note on multilingual setup

Bolna supports multilingual configurations, but with a key restriction:

You can use English plus one additional language in a single agent.

Examples of valid combinations:

• “English + Hindi”
• “English + French”
• “English + Spanish”
• “English + Marathi”
• “English + X”

Examples of invalid combinations:

• “English + Hindi + Marathi”

Prompting for non-english language

If you want to switch languages dynamically you can instruct the prompt to follow the customer’s language. For example, for Spanish you may write:

You will keep your sentences short and crisp. You will never reply with more than 2 sentences at a time. You will stick to context throughout. You must speak in Spanish but if the customer wishes to communicate in English, you will immediately shift your language to English and then remain in english. Generate the text response in the same language as the customer.

Write the prompt in the native script

Using the correct script:

• Enables more accurate pronunciation
• Helps the AI identify the intended language
• Improves contextual understanding and tone
• Prevents misclassification as English

​

Tips for Writing in native scripts

• Use Google Input Tools or built-in language keyboards on your phone/laptop.
• For European languages, make sure to include accented characters (like é, ñ, ü, ¿, ç, etc.).
• Double-check spellings and punctuation using tools like Google Translate, but avoid relying on it for full sentence correctness.
