Astra Lite lets you build voice bots that use your own recorded audio. The bot plays your audio to callers and listens for trigger words to determine the next action. Best suited for influencers and structured call flows.

Bot list

The main screen shows all your Astra Lite bots. Each entry displays:
  • Bot name
  • Telephony provider (Smartflo or Exotel)
  • Agent intercom number
  • Language and trigger words
Click Create New to add a bot.

Creating a bot

1

Set bot details

Provide a bot name, select your telephony provider (Smartflo or Exotel), and choose the transcription language.
2

Configure call behavior

Set the agent intercom number for call transfers. Define trigger words (comma-separated) that the bot listens for after playing audio.
3

Tune detection settings

  • Max words (1–10, default 3) — ignores utterances longer than this to prevent false triggers
  • Listening window (3–30 seconds, default 8) — how long the bot listens after audio finishes
  • Transfer on timeout — transfer to an agent or disconnect when listening times out
4

Configure webhook (optional)

Set a webhook URL, method (POST/GET), custom headers, and query parameters to receive call events.

Supported languages

Tamil, Hindi, Telugu, Kannada, Malayalam, English, Marathi, Bengali, Gujarati, Punjabi, and Urdu.

Managing audio

Each bot requires an audio file that plays during the call. From the bot’s menu:
  • Upload audio — select a file (MP3, WAV, OGG, FLAC, M4A, AAC, WMA, WebM, AMR)
  • Play audio — preview the uploaded recording
  • Delete audio — remove the audio file
A bot without an uploaded audio file will have nothing to play during calls. Upload your audio before activating the bot.

Testing

Select Test Bot from the menu to open a voice tester. This connects via WebSocket to simulate a live interaction.
