Audio Language Models for Speech Understanding

Language models that take audio as input to transcribe, answer questions about and converse over speech, sound and music.

Tier Grades

feasible

Tier A: Frontier AI labs

feasible

Mistral and Moonshot built these with 106 and 40 authors and 13 million hours of audio.

stretch

Tier B: Indonesian AI labs

stretch

Continued pre-training of an LLM on audio is possible only at far smaller scale than Kimi-Audio's 13 million hours.

not feasible

Tier C: Institution units such as ITB

not feasible

A unit cannot assemble 13 million hours of audio or a team of 40 or more, though it can evaluate released models.

feasible

Tier D: Organisations such as SEMAI (PoT, PoC, PoV)

feasible

Open models such as Voxtral under Apache 2.0 can be used directly for long meeting audio up to 40 minutes.

Where this comes from
Tiers: a) frontier AI labs, b) Indonesian AI labs, c) institution units such as ITB, d) organisations such as SEMAI delivering proof of technology, concept and value. Each rationale cites the anchors below.

Anchors

  • ComputeNot in the sources read: the Voxtral and Kimi-Audio abstracts give no parameter count or training compute; Kimi-Audio is initialised from a pre-trained LLM.
  • DataKimi-Audio: more than 13 million hours of speech, sound and music for pre-training; Voxtral: 32K context handles audio up to 40 minutes.
  • Team size (proxy)Proxy only (author count of an exemplar paper, not a headcount): 106 authors on Voxtral; 40 listed on Kimi-Audio.
  • Time horizonMonths to a year.
  • Shelf-life signalsGeneral multimodal models matching dedicated recognisers on transcription accuracy and cost
  • Pipeline roleTier A trains audio language models; Tier B and Tier C evaluate them on Indonesian speech; Tier D uses them for meeting minutes and call analysis pilots.
Where this comes from
Team size is a proxy (author counts of exemplar papers), not a headcount.

Who and What

Papers

Where this comes from
The papers to read first: where the direction began, its current best, and a survey when one exists.
