telnyx-tts-python

telnyx-tts-python is a skill for Claude Code, Codex from team-telnyx/ai. It costs 60 tokens per session (1,457 once invoked), scanned A, original, MIT.

A Python tool for turning written text into spoken audio through Telnyx and several other text-to-speech providers. It can return audio as encoded data or as a binary stream, and can list available voices.

In plain words
What is it for?
Use it to generate voice audio from text, choose or inspect provider voices, and handle speech API responses in Python.
Why use it?
It removes the need to integrate each speech provider separately. It also documents common network, authentication, validation, and rate-limit errors.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

telnyx-tts-python scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Telnyx Text-to-Speech - Python

Installation

pip install telnyx

Setup

import os
from telnyx import Telnyx

client = Telnyx(
    api_key=os.environ.get("TELNYX_API_KEY"),
)

All examples below assume client is already initialized as shown above.

Error Handling

All API calls can fail with network errors, rate limits (429), validation errors (422), or authentication errors (401). Always handle errors in production code:

import telnyx

try:
    response = client.text_to_speech.generate(text="Hello world")
except telnyx.APIConnectionError:
    print("Network error — check connectivity and retry")
except telnyx.RateLimitError:
    import time
    time.sleep(1)
except telnyx.APIStatusError as e:
    print(f"API error {e.status_code}: {e.message}")

Common error codes: 401 invalid API key, 403 insufficient permissions, 404 resource not found, 422 validation error, 429 rate limited.

Core Tasks

Generate speech from text

Generate synthesized speech audio from text input. Returns audio as base64-encoded JSON (base64_output) or a binary audio stream (binary_output).

POST /text-to-speech/speech

Parameter Type Required Description
text string Yes The text to synthesize.
provider enum No TTS provider: telnyx, aws, azure, elevenlabs, minimax, resemble, rime. Default: telnyx.
voice string No Voice ID to use (e.g., en-US-Standard-A for AWS).
output_type enum No binary_output or base64_output. Default: binary_output.
text_type enum No text or ssml. Default: text.
language string No Language code (e.g., en-US).
voice_settings object No Advanced voice settings (speed, pitch, volume).
telnyx object No Telnyx-specific provider options.
aws object No AWS-specific provider options.
azure object No Azure-specific provider options.
elevenlabs object No ElevenLabs-specific provider options.
minimax object No MiniMax-specific provider options.
resemble object No Resemble-specific provider options.
rime object No Rime-specific provider options.
disable_cache boolean No Disable response caching.
