In-car voice function calling (5500 examples)
Synthetic dataset of in-vehicle voice queries paired with tool calls, designed for fine-tuning LFM2.5-Audio-1.5B for end-to-end audio-in / tool-call-out function calling.
At a glance
| Train | Eval | |
|---|---|---|
| Examples | 5000 | 500 |
| Tools | 25 in-car functions across 7 categories | same |
| Audio | Kokoro TTS, 28 English voices, max 5% per voice | same |
| Complexity tiers | All 8 (Audio2Tool) | same |
Tool taxonomy (7 categories, 25 tools)
- Climate (4): set_temperature, set_fan_speed, defrost, sync_climate_zones
- Navigation (5): set_destination, find_nearest_poi, get_eta, add_via_point, cancel_route
- Media (5): play_song, pause_media, skip_media, set_volume, tune_radio
- Phone (3): call_contact, send_text, read_messages
- Vehicle (5): get_fuel, get_range, lock_vehicle, open_sunroof, set_driving_mode
- Settings (3): set_seat_position, set_ambient_light_color, set_seat_heating
- Conversational fallback: weather, time, general Q&A → trigger no tool call

Complexity tiers (Audio2Tool framework)
| Tier | Type | Train | Eval |
|---|---|---|---|
| 1 | Direct command ("pause") | 1172 | 118 |
| 2 | Parametric ("set temp to 72") | 1376 | 137 |
| 3 | Multi-intent | 492 | 49 |
| 4 | Implicit / pragmatic ("I'm freezing") | 589 | 59 |
| 5 | Needle-in-haystack (long chatter + command) | 437 | 43 |
| 6 | Self-correction | 299 | 30 |
| 7 | Multi-turn (4-8 turns + prior_turns) | 440 | 44 |
| 8 | Intent blending (primary + background speaker) | 195 | 20 |
Usage
from datasets import load_dataset
ds = load_dataset("potsawee/lfm-audio-fc-5500")
ex = ds["train"][0]
ex["user_audio"] # {"array": np.ndarray, "sampling_rate": 24000, "path": ...}
ex["expected_tool_call"] # "<|tool_call_start|>[func(args)]<|tool_call_end|>"
ex["expected_response"] # spoken confirmation text
ex["complexity_tier"] # 1-8
For tier-7 multi-turn examples, prior_turns_json is a JSON string. Resolve the inner audio_path against the audio/ folder in this repo:
import json
from huggingface_hub import hf_hub_download
prior = json.loads(ex["prior_turns_json"])
for turn in prior:
if turn["role"] == "user":
wav_path = hf_hub_download(
"potsawee/lfm-audio-fc-5500",
filename=turn["audio_path"].replace("data/", ""), # e.g. "audio/b026_010_pt0.wav"
repo_type="dataset",
)
Data format details
- Tool calls follow LFM2-1.2B-Tool format:
<|tool_call_start|>[func(arg=val)]<|tool_call_end|>followed by a spoken confirmation. Multi-intent (tier 3) emits multiple call blocks separated by - Tier-8 examples: the
user_audiois already the mixed primary + background. Thebackground_utterancefield gives the background text (different speaker, ~-10 dB).
Generation
- Text: synthesized by a Claude Code session reading per-batch instructions; stratified across 8 tiers × 7 categories × 6 example types; filtered + deduped to 5500 from ~6350 raw.
- Audio: Kokoro TTS v1.0, all 28 English voices, deterministic voice per example id (MD5-hashed). Tier-7 prior user turns use the same voice as the primary (same speaker). Tier-8 background uses a different voice, mixed at -10 dB.
- License: LFM Open License v1.0 (inherits from LFM2.5-Audio).
Limitations
- English only.
- Synthetic audio (Kokoro) — no real cabin acoustics, no real microphone characteristics, no real environmental noise. A light cabin-noise augmentation pass is planned but not applied in this release.
- 25 tools is a deliberately small taxonomy for prototyping; production assistants have hundreds.
