This benchmark measured an earlier version of the skill.
A newer attempt on gemini-3.8-flash on 10/19/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.
One of 9 test cases the skill fixed. Same model, same prompt, with and without the skill.
I am generating a voiceover using the ElevenLabs eleven_multilingual_v2 model. I need a half-second pause between two key sentences in the text string itself. How should the pause be inserted in the text argument?

The instructions your model reads when the skill loads.
Requires ELEVENLABS_API_KEY in .env.
from elevenlabs.client import ElevenLabs
from elevenlabs import save, VoiceSettings
import os
client = ElevenLabs(api_key=os.getenv("ELEVENLABS_API_KEY"))
audio = client.text_to_speech.convert(
text="Welcome to my video!",
voice_id="JBFqnCBsd6RMkjVDRZzb",
model_id="eleven_multilingual_v2",
voice_settings=VoiceSettings(
stability=0.5,
similarity_boost=0.75,
style=0.5,
speed=1.0
)
)
save(audio, "voiceover.mp3")
| Model | Quality | SSML Support | Notes |
|---|---|---|---|
eleven_multilingual_v2 | Highest consistency | None | Stable, production-ready, 29 languages. Toolkit default; supports style + speed |
eleven_v4 | Most expressive | None (audio tags, IPA) | Newest (released 2026-09-28), 90+ languages, best clone accuracy. Stability + similarity only, no style/speed |
eleven_flash_v2_5 | Good | <break>, <phoneme> | Fastest, cheapest; supports pause/pronunciation tags |
eleven_v3 | Expressive | None | Previous generation — prefer v4 |
Choose: multilingual_v2 for reliability and speed/style control, v4 for maximum expressiveness and cloned voices (test a few takes), flash for SSML control.
Deprecated: eleven_turbo_v2_5 → use eleven_flash_v2_5 (same quality, lower latency; see deprecated models). The toolkit still accepts --model eleven_turbo_v2_5: it prints a one-line warning and sends eleven_flash_v2_5.
