What it does
Voice Memo is an agent skill from letta-ai/lettabot. Reply with voice memos using text-to-speech. Use when the user sends a voice message, asks for an audio reply, or when a voice response would be more natural.
Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.
It sits in Media & Creative, covering Transcription and Text to speech and voice. It works with Telegram. The repository describes itself as: Archived - has been replaced by Letta Code channels/schedules! The licence is Apache-2.0.
When your agent uses it
- The user sends a voice message
- Asks for an audio reply
- A voice response would be more natural
Example prompts
- “/voice-memo”
Requirements
- A credential in ELEVENLABS_API_KEY
What it can do on your machine
Read from SKILL.md and the folder at commit 99c3b5d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
ELEVENLABS_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Voice Memo loads about 487 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 218 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- Reply with voice memos using text-to-speech. Use when the user sends a voice message, asks for an audio reply, or when a voice response would be more natural.
Voice Memo Responses
Generate voice memos using TTS and send them as native voice notes.
Usage
Use the <voice> directive to send voice memos. No tool calls needed:
<actions>
<voice>Hey, here's a quick update on that thing we discussed.</voice>
</actions>With accompanying text:
<actions>
<voice>Here's the summary as audio.</voice>
</actions>
And here it is in text form too!Silent mode (heartbeats, cron)
For background tasks that need to send voice without a user message context:
OUTPUT=$(lettabot-tts "Your message here") || exit 1
lettabot-message send --file "$OUTPUT" --voiceWhen to Use Voice
- User sent a voice message and a voice reply feels natural
- User explicitly asks for a voice/audio response
- Short, conversational responses (voice is awkward for long technical content)
When NOT to Use Voice
- Code snippets, file paths, URLs, or structured data (these should be text)
- Long responses -- keep voice memos under ~30 seconds of speech
- When the user has indicated a preference for text
- When
ELEVENLABS_API_KEYis not set
Notes
- Audio format is OGG Opus, which renders as native voice bubbles on Telegram and WhatsApp
- Discord and Slack will show it as a playable audio attachment
- Use
cleanup="true"to delete the audio file after sending - The
data/outbound/directory is the default allowed path for send-file directives - The script uses
$LETTABOT_WORKING_DIRto output files to the correct directory - On Telegram, if the user has voice message privacy enabled (Telegram Premium), the bot falls back to sending as an audio file instead of a voice bubble. Users can allow voice messages via Settings > Privacy and Security > Voice Messages.
