πππOur survey paper "Recent Advances in Speech Language Models: A Survey" has been accepted to ACL 2025 main conference!
This is the Github repository for paper: Recent Advances in Speech Language Models: A Survey. In this paper, we survey the field of Speech Language Models (SpeechLMs), which are capable of performing end-to-end speech interactions with humans and serve as autoregressive foundation models.
Why SpeechLMs? SpeechLMs are used for end-to-end speech-based interactions. Traditional ASR + LLM + TTS setups suffer from information loss and cumulative errors during conversion. SpeechLMs directly model speech data, capturing both semantic and paralinguistic information for richer interactions!
In this repository, we distinguish between two closely related model families:
Models supporting both text and speech output are listed under SpeechLMs to avoid duplication.

We introduce a novel taxonomy for SpeechLMs, categorizing them based on their architecture and training recipes.

The models below support speech/audio input and speech/audio output within the model. The list covers turn-based, streaming, and full-duplex interaction.
These entries are tracked separately because public information may describe a product or API rather than disclose a standalone end-to-end model architecture.
| System | Release | Year | Notes |
|---|---|---|---|
| OpenAI GPT-Live | Introducing GPT-Live | 2026 | Full-duplex voice model |
| OpenAI GPT-Realtime-2 | Advancing Voice Intelligence with New Models in the API | 2026 | Native audio input and output |
| OpenAI gpt-realtime | Introducing gpt-realtime | 2025 | Native audio input and output |
| Gemini Native Audio / Live API | Live API Capabilities | 2025 | Native real-time audio interaction |
| OpenAI Advanced Voice Mode | Advanced Voice Mode FAQ | 2024 | Commercial voice experience |

| MindGPT-4o-Audio | MindGPT-4o-Audio Release | 2025 | Commercial real-time voice model |
These papers improve the interaction behavior of full-duplex SpeechLMs rather than introducing a separate foundation-model family.
| Paper | Year | Focus |
|---|---|---|
| Aligning Spoken Dialogue Models from User Interactions | 2025 | Preference alignment from user interactions |
| Multi-Faceted Interactivity Alignment in Full-Duplex Speech Models | 2026 | Reinforcement learning for full-duplex interactivity |
LALMs accept speech, environmental sound, and/or music and generate text. Models that additionally generate speech are listed only in the SpeechLM section above.

The following works are closely related but are not included in the strict SpeechLM or LALM lists because they do not provide a unified speech-input/speech-output dialogue model or an audio-conditioned generative text LLM.
