+title: Speech
+description: Turn text into spoken audio with text-to-speech models.
+---
+
+Speech models read text aloud. Ollama streams the audio as it is generated, so playback can start before the whole text has been spoken.
+
+## Setup
+
+Start [Ollama](/quickstart) v0.40.9 or later, then download [Phonon](https://ollama.com/library/phonon):
+
+```shell setup.sh
+ollama pull phonon
+```
+
+Phonon uses Gradium's 31M English checkpoint and comes with Gradium's English voices, such as `Zoey`, `Easton`, and `Freya`. Without a voice, it speaks with the checkpoint's own voice, `default`. `ollama show phonon` lists every voice. Voice names work in any case and with or without accents.
+
+## Speak from the terminal
+
+`ollama run` plays the audio through your computer's speakers:
+
+```shell examples.sh
+# Speak some text
+ollama run phonon "Hello from Ollama."
+
+# Choose a voice
+ollama run phonon --voice Zoey "Hi, this is Zoey."
+
+# Speak text from another program
+echo "Text from another program works too." | ollama run phonon
+
+# Speak a chat model's answer
+ollama run gemma4 --hidethinking "Tell me a fun fact about owls in two sentences." | ollama run phonon
+```
+
+Piped text is spoken as it arrives, so a chat model's answer starts playing after its first sentence or two.
+
+Run `ollama run phonon` without any text to type lines at a `>>>` prompt. Each line is spoken when you press Enter. Press Ctrl+C to stop speaking, and type `/bye` or press Ctrl+D to exit.
+
+Audio plays with your system's built-in player: `afplay` on macOS, the first of `paplay`, `pw-play`, `aplay`, or `ffplay` that is installed on Linux, and PowerShell on Windows.
+
+### Save audio to a file
+
+When the output is redirected, `ollama run` writes a WAV file instead of playing it. This also works on servers without speakers:
+
+```shell
+ollama run phonon "Save this to a file." > speech.wav
+```
+
+To hear a remote server, run `ollama` on your own computer and point it at the server. The audio plays where the command runs:
+
+```shell
+OLLAMA_HOST=my-server:11434 ollama run phonon "Hello from the server."
+```
+
+## Generate speech with the API
+
+Use the OpenAI-compatible `/v1/audio/speech` endpoint:
+
+
+
+ ```shell
+ curl http://localhost:11434/v1/audio/speech \
+ -H "Content-Type: application/json" \
+ -d '{
+ "model": "phonon",
+ "input": "Hello from Ollama.",
+ "voice": "default"
+ }' --output speech.wav
+ ```
+
+
+ ```python
+ from openai import OpenAI
+
+ client = OpenAI(base_url="http://localhost:11434/v1", api_key="ollama")
+
+ with client.audio.speech.with_streaming_response.create(
+ model="phonon",
+ voice="default",
+ input="Hello from Ollama.",
+ response_format="wav",
+ ) as response:
+ response.stream_to_file("speech.wav")
+ ```
+
+
+ ```javascript
+ import fs from 'node:fs'
+ import OpenAI from 'openai'
+
+ const openai = new OpenAI({ baseURL: 'http://localhost:11434/v1', apiKey: 'ollama' })
+
+ const response = await openai.audio.speech.create({
+ model: 'phonon',
+ voice: 'default',
+ input: 'Hello from Ollama.',
+ response_format: 'wav',
+ })
+ fs.writeFileSync('speech.wav', Buffer.from(await response.arrayBuffer()))
+ ```
+
+
+
+The response streams while audio is generated, so you can start playing it right away:
+
+```shell
+curl -sN http://localhost:11434/v1/audio/speech \
+ -H "Content-Type: application/json" \
+ -d '{"model": "phonon", "input": "Playback starts while the rest is still being generated."}' \
+ | ffplay -nodisp -autoexit -loglevel error -
+```
+
+### Audio formats
+
+| `response_format` | Output |
+| --- | --- |
+| `wav` (default) | A WAV file: 16-bit, mono, 24 kHz. The header is written before the length is known, so its size fields hold the maximum value. |
+| `pcm` | Raw 16-bit little-endian samples, mono, 24 kHz, with no header. |
+
+### Limits
+
+- `input` can be up to 4,096 characters per request. `ollama run` splits longer text at paragraph and sentence breaks for you.
+- Prices, numbers, symbols, email addresses, and URLs are spelled out before speaking, so `$4.59` is read as "4 dollars and 59 cents". Times and numeric dates are read as written, so write dates out (`October 23`, not `10/23`) for a natural reading. Emoji, bullet characters, and markdown markers such as `*` and `#` are skipped.
+- Options the model doesn't support, such as other formats, speeds, or `instructions`, return a `400` error instead of being ignored. An unknown voice returns a `400` error that lists the available voices.
+- Speech models only generate speech: chat, completion, and embedding requests to them return a `400` error.
+
+`ollama show phonon` and `/api/show` list the model's capabilities as `speech`, and its voices (`voices` in `/api/show`). See [OpenAI compatibility](/api/openai-compatibility) for every supported field.

You can also use [OpenAI](/api/openai-compatibility) or [Anthropic](/api/anthropic-compatibility) clients. Each supports a subset of the original API. For endpoint schemas and response fields, see the [API Reference](/api/introduction).
